Preparation Of Oxalate Complexes Of Iron Biology Essay

Preparation Of Oxalate Complexes Of Iron Biology Essay To prepare two oxalate complexes of iron namely, Potassium Trioxalatoferrate Trihydrate and Iron Oxalate and to analyse the products for iron and oxalate respectively. One of the properties known to be characterised by transition metals such as iron is complex ion formation since they are able to form stable complexes. In this experiment, two complex of iron are being formed with the oxalate ion being the common ligand in both. Potassium Trioxalatoferrate (III) Trihydrate and Iron (II) Oxalate are the two complexes being formed and are represented by the following chemical structures: Figure 1: Chemical structures of Potassium Trioxalatoferrate (III) Trihydrate and Iron (II) Oxalate respectively. The oxalate ion, apart from acting as a Lewis base can be referred to as a bidentate ligand since an oxalate ion can donates two pairs of electrons (one from each oxygen) to the iron (III) or Iron (II) cation acting as a Lewis acid from two oxygen atoms as can be seen in figure 1 above. Iron can form a variety of complexes with most of them having an octahedral geometry. In this experiment, the Iron (II) oxalate formed is characterised by an Fe2+ as the central metal cation. This is then oxidised to Fe3+ in order to synthesise the Potassium Trioxalatoferrate (III) Trihydrate complex characterised by an Fe3+ as the central metal cation. Certain complexes such as the Potassium Trioxalatoferrate (III) Trihydrate complex are unstable to light and therefore they are said to be photosensitive. For this reason, it is a must to store such a complexes under dark conditions in order to prevent the reduction of the Fe3+ ion back to the Fe2+ ion. The amount of oxalate within a complex can be determined using titrimetric analysis. Potassium permanganate is titrated with the oxalate ion and the amount of oxalate can be determined through this redox titration. No indicator is necessary in such a titration due to the fact that the endpoint is characterised by a faint pink colour resulting from the fact that at the end point, excess un reacted permanganate ions are present in the solution since all the oxalate ions would have been consumed. The amount of iron in a complex on the other hand can be analysed following the addition of zinc to the complex solution followed by heating. Once this is carried out, the resulting solutions can be treated with potassium permanganate in a redox titration as described previously above and hence, the amount of iron in a complex can be determined. In this experiment, heating is involved in the redox titrations due to the fact that since the reaction is rather slow at room temperature, in order for one to observe a quick colour change at the end point, the solution needs to be heated to around 60oC. Method Chemicals used Ferrous ammonium sulphate Hydrogen peroxide Sulfuric acid Ethanol Oxalic acid Zinc Ferrous oxalate Potassium permanganate Potassium oxalate Apparatus used Buchner funnel Heating mantle Burette Weighing boat Thermometer Filter paper Magnetic stirrer Glass wool Analytical balance Measuring cylinder Procedure Part a Preparation of Iron (II) oxalate 15g of ferrous ammonium sulphate were dissolved in 50mL warm water which had been acidified with 1mL 2M sulfuric acid. To this, a solution of 10% 75mL oxalic acid was added with rapid stirring. The mixture was gently heated until its boiling point was reached and the yellow precipitate of ferrous oxalate formed was allowed to settle. The precipitate was removed by filtration on a Buchner funnel and washed thourally with hot water followed by acetone. The product was allowed to dry on a funnel under suction and was then weighed. Part B Preparation of Potassium Trioxalatoferrate (III) Trihydrate. 3.25g of ferrous oxalate was suspended in a warm solution of (5g in 15mL water) potassium oxalate. To this, 15mL 20 vol. Hydrogen peroxide was added from a burette whilst the solution was stirred continuously and the temperature was maintained at 40oC. The solution contained a precipitate of ferric hydroxide and this was removed by heating the solution to its boiling point and adding 10mL 10% oxalic acid. Further small amounts of oxalic acid was added drop wise until the precipitate just dissolved. The hot solution was filtered and 15mL ethanol was added to the filtrate in order to re dissolve any crystals that formed by gentle heating. The solution was placed in a dark cupboard to crystallize since the product formed was photosensitive. The crystals were collected by filtration on a Buchner funnel and later washed with an equivolume mixture of ethanol and water followed by acetone. The crystals were then dried and weighed. Part C The analysis of the products for Iron and Oxalate For Iron (II) oxalate: 0.3g of oxalate were dissolved in 25mL 2M sulfuric acid and the solution was heated to 60oC and titrated with 0.2M standard potassium permanganate solution until the first permanganate pink colour was observed. 2g of zinc dust was added and the solution was boiled for 25 minutes. The solution was filtered through glass wool and the residual zinc was washed with 2M sulfuric acid. The washings were added to the filtrate and the solution was titrated with standard potassium permanganate. The percentages of iron, oxalate and water of recrystalisation in the product were determined and hence, the empirical formula could be derived. For Potassium trioxalatoferrate (III) trihydrate: 0.2g of Potassium trioxalatoferrate (III) trihydrate were dissolved in 25mL 2M sulfuric acid and titrated with 0.02M permanganate. The solution was treated with zinc dust and re-titrated with permanganate as described in the analysis of Iron (II) oxalate above. The percentages of iron and oxalate in the complex were determined and this was compared to the theoretical value. Precautions: It was made sure that in the preparation of Potassium Trioxalatoferrate (III) Trihydrate, ethanol was added to the filtrate in order to re dissolve any crystals that formed by gentle heating. It was made sure that in the preparation of Potassium Trioxalatoferrate (III) Trihydrate, the solution was placed in a dark cupboard to crystallize since the product formed was photosensitive. It was made sure that for the preparation of Potassium Trioxalatoferrate (III) Trihydrate, the temperature was maintained at 40oC to prevent hydrogen peroxide decomposition. Observations: Ferrous (II) oxalate had a yellow precipitate and at the end a yellow powder was obtained. The endpoint of the redox titrimetric titration was marked by a faint pink colouration. Ferric hydroxide had a brown precipitate which turned into a green solution upon excess oxalic acid was added. Potassium Trioxalatoferrate (III) Trihydrate formed was in the form of green crystals. 3. Results and Calculations Results: Part A: Ferrous ammonium sulphate weighed 15.042g 10% oxalic acid measured 75mL Mass of ferrous (II) oxalate obtained 5.586g Part B: Ferrous (II) oxalate used 3.269g Potassium oxalate used 5.008g Mass of Potassium Trioxalatoferrate (III) Trihydrate obtained 2.205g Part C: Ferrous (II) oxalate used 0.320g Potassium Trioxalatoferrate (III) Trihydrate used 0.200g Zinc used 2g Volume of permanganate required in the redox titration between iron (II) oxalate and permanganate 49.5mL Volume of permanganate required in the redox titration between iron (II) oxalate and permanganate in the presence of zinc 15.50mL Volume of permanganate required in the redox titration between Potassium Trioxalatoferrate (III) Trihydrate and permanganate 24.50mL Volume of permanganate required in the redox titration between Potassium Trioxalatoferrate (III) Trihydrate and permanganate in the presence of zinc 4.00mL Calculations: Analysis of products for Iron Oxalate for Iron(II) oxalate The equations taking place in the reaction are: 2MnO4- (aq) + 5C2O42- (aq) + 16H+ (aq) Æ’Â   2Mn2+ (aq) + 10CO2 (g) + 8H2O (l) 5Fe2+ + MnO4- + 8H+ Æ’Â   5Fe3+ + Mn2+ + H2O Moles permanganate reacting with oxalate and iron = Concentration of permanganate x Volume of permanganate required: Moles permanganate = 0.02 x (49.50 / 1000) Moles permanganate = 0.00099 moles Moles permanganate reacting with iron (II) = Concentration of permanganate x Volume of permanganate required: Moles permanganate = 0.02 x (15.5 / 1000) Moles permanganate = 0.00031 moles Therefore, moles of permanganate reacting with the oxalate ions = Total number of moles Number of moles of permanganate reacting with iron. 0.00099 0.00031 = 0.00068 moles From the stoichiometry of the equation it is observed that 2 moles of permanganate react with 5 moles of oxalate, thus: Moles of oxalate = 5/2 (0.00068) = 0.0017 moles Grams of oxalate = number of moles x mass of oxalate Grams of oxalate = 0.0017 x 88 Grams of oxalate = 0.150 grams Therefore % oxalate in the product: (0.150 / 0.320) x 100 = 46.9 % From the stoichiometry of the equation it is observed that 1 mole of permanganate react with 5 moles of Iron, thus: Moles of oxalate = 5 (0.00031) = 0.00155 moles Grams of Iron (II) = number of moles x mass of oxalate Grams of Iron (II) = 0.00155 x 56 Grams of Iron (II) = 0.087 grams Therefore % Iron in the product: (0.087 / 0.320) x 100 = 27.19% The mass of water = Total mass of complex (Mass of oxalate + iron (ii)) Mass of water = 0.320 (0.150 + 0.087) = 0.083g Therefore moles = grams / RMM Moles water = 0.083 / 18 Moles water = 0.0046 moles Therefore % water in product: (0.083 / 0.320) x 100 = 25.9% To calculate the empirical formula: Iron Oxalate Water 0.00155 : 0.0017 : 0.0046 0.00155 : 0.00155 : 0.00155 1 : 1 : 3 Thus empirical formula is FeC2O4.3H2O Analysis of products for Iron Oxalate for Potassium trioxalatoferrate (III) trihydrate. The equation taking place in the reaction are: 2MnO4- (aq) + 5C2O42- (aq) + 16H+ (aq) Æ’Â   2Mn2+ (aq) + 10CO2 (g) + 8H2O (l) 5Fe2+ + MnO4- + 8H+ Æ’Â   5Fe3+ + Mn2+ + H2O Moles permanganate reacting with oxalate = Concentration of permanganate x Volume of permanganate required: Moles permanganate = 0.02 x (24.5 / 1000) Moles permanganate = 0.00049 moles From the stoichiometry of the equation it is observed that 2 moles of permanganate react with 5 moles of oxalate, thus: Moles of oxalate = 5/2 (0.00049) = 0.00123 moles Grams of oxalate = number of moles x mass of oxalate Grams of oxalate = 0.00123 x 88 Grams of oxalate = 0.108 grams Therefore % oxalate in the product: (0.108 / 0.200) x 100 = 54 % Moles permanganate reacting with iron (III) = Concentration of permanganate x Volume of permanganate required: Moles permanganate = 0.02 x (4.00 / 1000) Moles permanganate = 810-5 moles From the stoichiometry of the equation it is observed that 1 mole of permanganate react with 5 moles of Iron, thus: Moles of oxalate = 5 (810-5) = 0.0004 moles Grams of Iron = number of moles x mass of oxalate Grams of Iron = 0.0004 x 56 Grams of Iron = 0.0224 grams Therefore % Iron in the product: (0.0224 / 0.200) x 100 = 11.20% Discussion: In the first part of the experiment, ferrous ammonium sulphate, also known as Mohrs Salt was treated with warm water and sulphuric acid in order to prevent the formation of rust coloured iron hydroxides and oxides. This was followed by oxalic acid. The oxalate ions replace some or all of the sulphate ligands surrounding the Fe2+ ion and as a result, a yellow precipitate of ferrous oxalate forms. The reaction taking place is as follows: H2C2O4 (aq) + Fe2+ (aq) + 2H2O (l) Æ’Â   3H2O+ (aq) + FeC2O4 (s) In order to oxidise the Fe2+ ion into an Fe3+ ion in ferrous oxalate, hydrogen peroxide, acting as an oxidising agent is added to a solution of ferrous oxalate and potassium oxalate. Temperature control is very crucial in this step due to the fact at high temperatures, hydrogen peroxide can decompose and thus would not be able to oxidise the iron (II) to iron (III) required to prepare the Potassium trioxalatoferrate (III) trihydrate complex. It is important to make sure that all the iron (ii) has been oxidised to iron (iii) due to the fact that since each complex consists of a different number of oxalate ligands, if a mixture of the two complex ions is present, the empirical formula determination would become difficult. The reaction taking place is as follows: 2FeC2O4 (s) + C2O42- (aq) + H2O2 (aq) + 2H3O+ (aq) Æ’Â   4H2O (l) + Fe2(C2O4 )3 (s) When the Fe2(C2O4 )3 precipitate was dissolved, [Fe(C2O4)3]3- forms. This reacts with the potassium ions in solution introduced via the potassium oxalate and forms potassium trioxalatoferrate (III) which is photosensitive and thus must be stored in the dark. In the analysis of the oxalate ion, no indicator is required in the redox titration between permanganate and the oxalate ions due to the fact that at the end point, since potassium permanganate is an oxidising agent, it oxidises the oxalate ions in solution into carbon dioxide and as a result, permanganate is itself reduced to Mn2+ therefore a faint pink colour is observed at the endpoint. The reactions taking place are as follows: 2MnO4- (aq) + 5C2O42- (aq) + 16H+ (aq) Æ’Â   2Mn2+ (aq) + 10CO2 (g) + 8H2O (l) In order to analyse the iron content in the complexes formed, zinc is added followed by heating the solution. Once this was complete, the solution was treated with permanganate in a redox titration similar to the one described previously above. The reaction taking place is as follows: 5Fe2+ + MnO4- + 8H+ Æ’Â   5Fe3+ + Mn2+ + H2O Conclusion: This experiment has shown that iron being a transition metal can exist as various oxidation states. These oxidation states can then form a variety of complexes with various ligands. The complexes that are formed can then be analysed using a redox titration in order to determine the percentages of iron and oxalate in the complex. In this experiment, the empirical formula of Iron (II) oxalate was found to be FeC2O4.3H2O and consisted of 46.9 % oxalate, 27.19% Iron (II) and 25.9% water where as the Trioxalatoferrate (III) Trihydrate consisted of 54% oxalate and 11.20% iron (III)

Hitlers Foreign Policy :: essays research papers fc

Assignment: Give an account of Hitler’s foreign policy, using the following headings: (A) Defiance of the Versailles Treaty (B) Relations with Italy (C) Territorial Expansion Defiance of the Versailles Treaty After the First World War, Germany signed a peace treaty with France and Britain. Among the 440 Articles were: * Germany lost Posen, the Polish Corridor and part of Upper Silesia to Poland. * Germany lost the Sudetenland to Czechoslovakia * Germany lost Eupen and Malmedy to Belgium * Germany lost North Schleswig to Denmark * Germany lost Alsace Lorraine to France * Germany lost all its overseas colonies * Saarland was under LN control and after 15 years the people could vote if they wanted to belong to Germany or France * The Rhineland was to be demilitarised * The army was reduced to 100,000 * Germany could have no submarines, no airforce and no heavy artillery * Germany had to pay major Reparations. In percentages: Germany lost 10% of its land, 100% of its colonies, 12.5% of its population 16% of its coal fields and 50% of its iron and steel industry. The main terms of the Versailles treaty Hitler (like most Germans) hated the Versailles Treaty and he didn’t want to follow the rules made by it. In fact, step by step he broke the laws. The first step he took was to increase the German army. Germany was only allowed to have an army of 100,000 men, no airforce, no tanks and no submarines. But in an interview with the Daily Mail on March 9, 1935, Goering revealed that there was a German airforce. One weak later Germany also announced that it had an army of 500,000 men. France and England didn’t even object to this. In 1936 Germany signed a treaty with England saying that Germany was allowed a navy one third the size of the British navy. Germany was rearming fast. It wasn’t hard thanks to the good economic growth. But the rearmament was so expensive that in 1936 it was clear that Germany was soon to go into an economic crisis if nothing was done. There wasn’t a better time to test the Versailles Treaty because the international situation was very fortunate to Hitler. Italy’s invasion of Ethiopia proved that the League of Nation (LN) was worthless. It also focussed Anglo-French diplomacy on Italy. After some years, Italy became weak because of the economic sanctions from Britain and France and the public opinion in France and Britain was still very anti-war.

Grapes of Wrath :: essays research papers

The Grapes of Wrath, chronicles the Joad’s family exodus from Oklahoma to California in search for a brighter, economic future. The name Joad and the exodus to California is parallel to the Biblical story of Exodus and the character Job, but at the time was depicting the Okie Exodus. The Okies were farmers whose topsoil blew away due to dust storms and were forced to migrate along Route 66 to California in search of work. The Okies were resented for migrating in large numbers to areas in the West where work was already hard to find and the sudden multitude of workers caused wages to be lowered. The Joad’s reside in Oklahoma, referred to as the â€Å"Dust Bowl† of the U.S. because of its lack of rain. The story takes place during the late 1930’s when the country was in the midst of the Great Depression. The Joad family were sharecroppers evicted from their homes because they failed to pay the bank their loan payments to the Shawnee Land and Cattle Company.   Ã‚  Ã‚  Ã‚  Ã‚  On their journey, the Joad’s ran into a returning migrant from California who tells them that the handbill they have looking for 800 pickers is a bunch of hogwash. He’d rather starve in Oklahoma then starve in California. The migrant scolds them on their naivety saying â€Å"Now, how many of you all got them handbills?...(The men respond that they all have them) There you are, same yellow handbill. 800 Pickers Wanted. All right, the man wants 800 men, so he prints 5,000 handbills and maybe 20,000 people see 'em. And maybe two or three thousand people start West on account of that handbill. Two or three thousand people that are crazy with worry headin' out for 800 jobs. Now does that make sense?† He tells them that the growers are exploiting them, causing a surplus of workers to drive down labor costs according to supply and demand. The significance of his role in the movie, is that he let’s the Joad’s know everything they are moving West for is false. Their journey is based on a lie, and the grass isn’t greener on the other side.   Ã‚  Ã‚  Ã‚  Ã‚  While stopping for gas, Mr. Joad heads into the diner to buy a loaf of bread. Mr. Joad is a nickel short of the 15 cents that the bread cost, and against the waitresses opinion the chef tells her to sell it to him for a dime.

Importance of Matrifocal family in the caribbean Essay

The Matrifocal family Is very prominent in the Caribbean. This is noted more as among people of Africans in the regions. Reasons for this diversity, Cultural Retention, Plantation system of slavery, SOCIO economic and the culture of property. Cultural retention, Melville Herkevitts was one of the first researchers to trace the African Origin of the slaves who came to the Americans he believed that despite attempts to strip Africans slaves ot their cultural heritage the practice ot polygyny was retained from the practice. affected by bonding and closeness of mother and child because the husband/ father was somewhat marginal. This pattern remained in the Caribbean society especially about lower class people of African descent. Plantation system, there is the belief that the persistence of the Matrifocal family can be seen as a consequence of the plantation system of slavery, M. C. Smith wrote that under plantation slavery stables families were not given a chance to develop unions of whatever sort, were often broken up as slaves were sold. The unit of mother and child was less likely to be torn apart than a unit of man, woman and child, males were denied family rights which resulted in a system of female centeredness therefore became marginalise. Women now lead their families. It is a well-organized social group which represents a positive adaptauon to the circumstances of poverty. By not tying herself down to a husband. the mother is able to maintain causal relationships with a number of men who can provide her with financial support. The above Information shows that the Matrlfocal family can be regarded as a form of family structure in its own right. It is therefore Important because it shows that a woman doesnt need a man to take care of her and her family, she If fully cable of performing both tasks all by herself. so Matrltocal family Is very Important.

Deviant Act Project: Visit to a Grocery Store

For my act of deviance I chose to go to a grocery store and attempt to pay for my groceries ignoring the line at the checkout counter. So one day I went to my local grocery store. After filling my shopping cart I headed towards checkout area. The closer I was getting there, the more vulnerable and hesitant felt. I was almost ready to give up this whole Idea when I got to the line, but then I heard: â€Å"Next person In line! † from a cashier on the right who has Just opened her checkout station. I quickly pushed my cart to that register and noticed a person (who was next in line to check UT) also going to that newly-opened register.I got there faster and put my first item on the counter. Nobody said anything to me. Several other people from the line moved to this cash register and formed a new line. I was putting my groceries on the counter. In the middle of me taking the groceries out of the cart I looked at the person standing next in line after me. This was a middle-aged wo man. With a frown on her face she stared straight back at me but did not say anything. I have also noticed that a person behind her was staring too. They both were not Just looking at e, they were staring in disapproval. I just smiled and turned back.I made sure I took my time at the register: I had a lot of groceries in my cart. I paid and left. Waiting line itself has been recognized to be a social system. The leading rule for this social system Is the First In First Out (FIFO) rule and all Intrusions are deviations from the norm. (Allan, Gad and Hanna, Reran. 2010. Cutting in Line: Social Norms in Queues. ) When waiting in line, we expect people also to wait their turn. When someone decides to cut in line: they violate a social norm. All those people In line must have en interested in enforcing conformity to the norm.Nobody likes to wait in lines and I am sure that they all would prefer to check out and leave the store faster. They clearly saw that I have Jumped the line but thos e stares and a frown were the only sanctions I have got for breaking the norm. I did not feel comfortable breaking the norm. It was hard to predict how exactly people would react to me and what kind of sanctions I would have to face. I am not sure what I would do if I got sanctioned in some other way, other than getting those stares and a frown. I don't know If I would Just tell the truth about my school assignment or if I would try to Justify my actions by lying.Now, if somebody would try to behave the same way in a country, where lines etiquette is different or does not exist at all, than this behavior would not be normal for people in a queue to let an old person go and check out first and not wait in line. Also, there was an example in our text book where author told us about his experience at one of the African countries where people would Just push or shove toward the ticket man if they needed to buy a ticket for a bus or train. (Heinlein, James M. 2011. Essentials of Sociolog y. A Down-to-Earth Approach. )

Injustice in the Adversarial System Essay

Donald Black discussed in his book The Behavior of Law, when a society begins to grow and become more complex so does its legal system. The United States uses a system that may no longer be fit for handling all the complex problems it is faced with. Society has come to learn through the justice system that truth is very hard to find. The nature of the adversarial process may prevent it from reaching the true goal of every legal system: justice. This writing argues that the system in place now is not the correct one for the stage society is in now. The adversarial process in place does not search for the core values of â€Å"Justice† and â€Å"Truth†; its inadequacies create errors in the legal system. The legal system should abolish its value of â€Å"winning at all cost† and the methods it uses to achieve this outcome. This paper will not only shed light on the flaws in the legal system, but present other structures that may be better suited for the present stage of society. Blueprint A few brief critiques of the adversarial process include that during a trial procedure both sides are given the opportunity to present facts to the jury or judge, this allows attorneys to withhold evidence and benefit the side they represent. This confuses the courts instead of elucidating the truth. Cases such as this should not be able to come to a guilty or not guilty verdict, because guilt cannot be proven with a degree of accuracy (Meadow, 1996). Stratification in law does lead to inequality and perpetuates injustice in society. The procedure that is used in our criminal justice system has the ability to lead to a false confession and create mistrust in the system. Bias in our legal system does lead to injustice. All of these factors do create injustice in our legal system by sending innocent people to prison and/or by letting convicted felons free. There are many theories in how to solve the problems with the adversarial process and the legal system in general, but society must change the way it reasons before anything can truly change. History of Common Law and the Adversarial Process To better understand the adversarial process it must first explain through its history and origins. Common law practice developed the adversarial process; England adopted common law and made its practice known throughout the world. Legislators began codifying the law, this later became common law. It was written so that it could be interpreted by the court system. When the courts make a decision in how that law is to be applied it is preserved, and able to be used as a guideline for other cases of the same nature. This proved to be a problem, decisions made by judges were based on the customs of the time period, which became rigid and did not easily allow for change (Cantor, 1997). The English form of common law prohibited representation in court however, during the eighteenth century some courts where beginning to allow legal representation in English common law. Eventually as time progressed, the role legal representation, lawyers, would grow and be more influential in society. The part the Lawyers played in the court system would eventually be the aspect that separated the adversarial process implemented today in the United States from the processes in England. Law became more and more complex so the use of lawyers or professionals of the law was essential in American law making. New research by Randolph N. Jonakait, New York Law School professor, suggests that the United States adopted an adversarial process that somewhat resembled the English model at the time. Besides the already mention use of lawyers, the U.S differed greatly from England, during the 18th century; America had prosecution with a public defender present in the court room compared to no legal representation for the accused in the English model. Also in New Jersey around the same time period, attorneys usually appeared for the prosecution and the defense which in England was rarely practiced. These findings demonstrate that the United States was a forerunner in the creation of the adversarial process that is present today (Jonakait, 2009). Search for Truth: Lawyers and Their Tactics One of the main concepts of the adversarial system is the oppositional presentation of facts. The belief behind this is it will discover all truths to the matter. This leads to the conclusion of the first flaw: that realistically everyone involved in the case is not in search of the truth. â€Å"Lawyers are more apt to hide the evidence that is not favorable to their side regardless of whether it would prove the innocence or guilt of the person on trial† (Schroeder, 2012). Clients hire lawyers to win; the economic state of the client is directly related to the skill level of the lawyer they can afford. Lawyers who are more expensive will use any tactics necessary to ensure a win. The search for truth is not a key value; it’s keeping your client pleased, being the defendant or the state. Attorneys are known to use questionable tactics so that they have the best possibility of winning their case. These tactics include: creating doubt in the jury of guilt or innocence, or even by hiding evidence from the jurors. The search for truth and the execution of justice cannot be fully performed if lawyers proceed to use unethical tactics. Solutions to the Hiding of Evidence A purposed solution to hiding evidence can be demonstrated with a value demonstrated from the inquisitorial system, everyone in the court room works together in search for the truth and justice. The judges, or investigative magistrate, are trained in their profession, taking specific schooling about law making them a vital resource to the legal system. While court is proceeding the judge is allowed to ask questions to keep a case in order. Using a system that does not glorify winning would help the hindering of evidence and other tactics being eradicated form the court room. Although, one flaw with this system is the judge is granted too much power and control over the proceeding, more justice is still found here searching for truth. Stratification in Law It is proven that â€Å"once arrested, black and minority defendants are fare worse in the criminal justice system than their white counter parts† (Westervely & Humphrey, 115, 2008). This is due to racial stratification in law and a bias based on race in convictions. Instrumentalist would say law is used to dominate groups, and is structured so that it can benefit certain groups by disadvantaging other groups, by allowing this to happen it perpetuates inequality (Bucher, 2012). Many minorities are unable to pay for legal representation; in this situation the courts provide representation for them. This disadvantages minority individuals in low social class because they lack resources to secure a good lawyer, while high social status clients are able to easily obtain skilled lawyers. This perpetuates stratification because upper class individuals can evade the penalties of the legal system, unlike lower class individuals who cannot afford strong legal representation (Vago, 2012). Marxist theorists would confirm that laws serve the interest of the upper class, and because they use them like a tool, keep the upper class in power. This reinforces inequality in society through the criminal justice system, because the upper class will always be able to have access to more resources they will also always use those resources against the lower class (Bucher, 2012). Process in Criminal Justice Is Justice Served? The pressure felt in a case created by media and the public eye have the ability to cause investigations to be sped up. The endangers the adversarial process to make mistakes and possibly out of convenience and pressure convict the first person they think committed the crime. Once police officers make an arrest they tend to not pursue any other possible leads until the person they have in custody is proven to be innocent. This hurts the search for truth because officers become close minded and search only for evidence to convict that individual. Another factor that can deter the search for truth is false confessions. False confessions, among other factors, are commonly created due to unethical interrogation tactics or confused eye witnesses testimony. â€Å"A confession is one of the most powerful pieces of evidence that can be presented in court† (Westervely & Humphrey, 36, 2008). Even if the confession is false, juries have been known to take into consideration testimony even when told not to. False confessions are usually given by suspects who are coerced, confused, have doubt in-self, or shame. All this can be attributed to the psychological games used by interrogators, intentional or unintentional (Gudjonsson, 1992). Can true justice be served when police use unethical tactics to get their confession? This is a question scholars who study ethics have pondered with for decades. Bias in Law There are many principles to consider when a jury is deciding a verdict. Racial beliefs, media and number of factors can influence a jury’s verdict (David F. Hall, 1984). Since each individual interprets the process of the trial differently it greatly influences the decision of case. The way society is socialized leads to certain bias to people of different races, genders, sexuality, and backgrounds. These factors greatly influence a cases outcome, even though lawyers are allowed to select their jury it is impossible to know each person individually (Albonetti and Hagan, 1982). In common law, legislature creates the laws that are written down and left for interpretation by the judges of the court, this is called statutory interpretation (Bucher, 2012). The strength of this system of law is the ability that law has to change; downfall is that it leaves room for bias in the interpretation of law. Some scholars suggest that law and the legal system is patriarchal. The feminist legal theory suggests that the legal system is male dominated and perpetuates gender discrimination (Bucher, 2012). Language can be biased in law; the United States suffers from this weakness. In the Declaration of Independence biased language is evident. â€Å"All Men Are Created Equal† a line from the Declaration of independence has brought forth discussion and conflict because of biases behind the words. Women have fought for their rights to be considered equal because society takes the patriarchal documents literal, progress is slowly made. Everything, including law, can be interpreted differently, making the judge’s job detrimental to the court process. The discretion of the authority in the court system, although important, also creates inconsistency in the legal system. African Americans account for 49.4 percent of the 1.3 million Americans in prison (Westervely & Humphrey, 2008). Two different theories can explain the bias in society that explains the high population of African Americans. These theories are the Individual Explanation Theory and the Structural Explanation Theory. Individual Explanation Theory This theory focuses on the behavior and traits of those involved in a trial. Racism is a factor in explaining why an innocent person is tried. This happens because the adversarial system does not focus on searching for the truth and allows the jury to makes a decision on beliefs and prejudices of a certain race. Stereotyping is also included when a jury convicts someone on account of preconceived notions of a group (Westervely & Humphrey, 2008). Structural Explanation Theory This theory provides two explanations for the bias. The first is the Blalocks Power-Threat Hypothesis. The hypothesis states that the increase in minority conviction is due to whites trying to keep power and control over minority races by disadvantaging them. The second explanation states that the treatment of minorities in the criminal justice system is a reflection of societal beliefs. â€Å"Equality in the criminal justice system is not possible until everything else is equal† (Westervely & Humphrey, 128, 2008). Plea-Bargains and its deficiencies Due to the amount of offenders that go through the U.S. court systems prosecutors are more likely to use plea-bargains to settle cases quickly. â€Å"It is estimated that roughly 90-95 percent of all criminal convictions are arrived through plea–bargains† (Vago, 118). This tactic can be linked to stratification and inequality, when a person on trial does not have the finances for a good lawyer the assumption is that they will lose. This makes a plea-bargain more appealing, as it is the best option to avoid a longer sentence (Kipnis, 1976). â€Å"The Standing Committee on Legal Aid and Indigent Defendants summarized the state of representation as follows: â€Å"Overall, there is abundant evidence in this report that defense services for the poor are inadequately funded. As a result, millions of persons who have a constitutional right to counsel are denied effective legal representation†Ã¢â‚¬  (Mosteller, 2011). This is another factor to cause change in the legal system so that truth can properly be found. The ability to plea-guilty hinders the search for truth and justice. In the inquisitorial system guilty pleas and plea-bargaining are not allowed so that the system can properly search for the truth. It does not give the accused rights, unlike the United States. While in the United States the adversarial process gives the accused the ability to plead guilty for a lesser sentence which some would consider â€Å"soft† on crime. In the adversarial process after a confession is given, the investigation is typically over even if the individual is innocent. In the inquisitorial system a confession is not warranted since it is the duty of the court to come up with evidence and prove guilt (Berger, 1972). Injustice With all this bias in our legal system this gives room for errors in justice. â€Å"An error in justice is any departure from an optimal outcome of justice for a criminal case† (Frost, 2004). There are two types of errors that can be described: systematic and random. Systematic is when there is an error within the law that consistently creates injustice. When a law is in enacted and it oppresses a certain group consistently this is systematic injustice. Random errors are created while criminal justice officials are enforcing the law and the error is sporadic (Frost, 2004). Both of these can create errors of due process, which is when the rights of the accused are violated. The first error is miscarriage of justice; an example of this is when an innocent man is convicted of a crime. The second type of error of due process is error of impunity, when an error in the procedure of due process is committed and as a result guilty convict is set free. Both of these do create great mistrust in the legal system and deter people from getting involved within its legal processes (Sherman, 2002). This can lead to what Black was suggesting when he stated that law will shift back to a more primitive family based form of sanctions, because of mistrust in the authority that was supposed to protect them. Change With new understandings of societal factors (race, gender, sexuality) the adversarial system needs to be revised so that it aids the search for truth or it will be blinded by these factors. Society has grown complex and so has its problems with in the legal system. The courts must come up with different resolutions for crimes and convictions, not just a â€Å"one size fits all solution†. In essence the adjudication system is not wrong, but the misuse of evidence and human error leads to mistakes. One might ask should we change the adversarial system entirely or fix the many flaws within the system. The current process being used relies on the state (prosecutor) to determine if the court should or shouldn’t present the evidence accumulated from the crime, or if that would benefit the accused in some way. All evidence should be given to a neutral party, such as the court, and have the court system decide what should be done. This would remove the ability of the prosecutor to hide facts that could be essential to the investigation (Westervely & Humphrey, 2008). In an ideal system the court should base their decision after learning all the facts, without any evidence withheld from either side. There can be a mixture of different processes, which can better achieve justice in a complex society. For example, a different process would be needed to determine if a dangerous criminal is guilty than that of finding parental rights. Forms such as the inquisitorial investigation, mediation, private problem-solving, group negotiating processes could be used to search for truth. Conclusion The adversarial systems values do not match what the goals of the system should be. In the ideal system restorative and rehabilitation justice would be utilized to the fullest in order to help the people going through the criminal justice process learn and become productive members of society. Society’s beliefs are that of retribution and vengeance. Society as a whole wants to see criminals punished for crimes that they feel where committed upon them. To completely change the beliefs of the criminal justice system, society needs to change its values from retribution and vengeance, to a form of justice that will help society instead of looking for revenge. Values in the criminal justice system represent what that society believes in. The belief in winning shouldn’t be enforced, like the adversarial process has done, because it does not accomplish what the main goal of the criminal justice system is: to provide justice to the citizens of the country the system serves, along with the search for truth. The values of rehabilitation and restoration should be the foundation on which we build our new system. If this is done than our society will begin to help its self in creating a strong nation that is just and true. References Albonetti, Celesta and Hagan, John.

Starbucks Assessment

Company name and brief background Starbucks is an American global coffee company which it is the largest coffeehouse company in the world. I think anybody know Starbucks that provide to enjoy the best coffee in the world. Starbuck brief background; the opening of the first Starbucks in 1970s which was small restaurant order to enjoy coffee and it was in the city of Seattle. At the same time many people liked to drink over milk coffee and chocolate coffee, so that was more and more popular.Nowadays, Starbucks is the largest coffeehouse company in the world, with 17000 stores in 60 countries including Canada, Japan, UK, South Korea, India, Hong Kong, Taiwan and Thailand so on. The Starbucks promotion its product or services The beginning Starbucks only sold coffee and espresso drink as well as coffee bean. Nowadays, it sells hot and cold drink, coffee bean, hot and cold sandwiches, sweets, salads, snakes and items such as mugs, glass and tumblers. Also, its products are seasonal. Howev er, it provides various services such as entertainment (music, newspaper, magazine, free internet), and offers good or quick services.How the promotion techniques used help the Starbucks to attempt to increase its sale. Well know, Starbuck is the world brand that itself have a certain visibility, so that it rarely uses advertising on television and magazine because it don’t spend a lot of money on advertising, but it used some advertisements on billboard. We find some billboard at the highway, building or station. In addition, it used short video upload on YouTube, Blog, social network ( e. g Facebook, Twitter),website. Also it is actually in the position of strength region which is the premium brand because it chooses the position in more streams of people.However, it grow into one of the world know brand. How Starbucks maintain customer loyalty Starbucks loves hearing from customer all question, comment that is always welcome while provides the experience of quality coffee and warm service. Also, it uses a various promotion different countries such as in Taiwan uses half price discount for the period. It offers fast-forward services and high quality coffee. In addition, the customer buy a Starbucks tumbler get one free drink. In Hong Kong Starbucks promotion is free internet. For example, f you buy Starbucks drinks that you use internet its shop also it offers free newspaper, magazine and comfortable environment area for the customer. It believes that many people love drinking Starbucks coffee because it twenty types of coffee so that customer can choose different taste coffee. However, more and more people like drinking Starbucks coffee. How the Trade Descriptions Act affects the way that Starbucks promotion its products and services Starbuck need to be aware of laws in every country, so that it has law for employment, health and safety regulation and product restriction.Beside Starbucks takes action to reduce waste for its operation and recycle, als o it considers preserve the earth’s natural resource and enhance the quality of live around the global. In addition to, Starbucks actively seeks opportunities to minimize environment impact and help create a healthy planet, so that it takes steps to be environmental mission statement. Most importantly, it improves coffee quality in order to have commitment to origin TM that helps to improve the lives of coffee farmers and protect the environment where they grow their beans and can keep its highest-quality coffee standard.It is imperative that Starbucks understand commodity–grade coffee to be trade on a highly competitive market. Obviously, for the last several years, a global oversupply of coffee has been getting high price. So that it keeps steady price standard. Specifically, it provides in the fair trade certification system for importer, roaster, and retailers purchases coffee at favorable guaranteed price from farmers who registered with Fairtrade Labelling Organi zation International.Overall, I think it is a role promotion in the business which is important. Many people want to have a success on their own business, but they don't have achievement of promotion, so that they will lose their business. On the other hand, Starbucks has a success promotion of business in the world. It is not only promotion activities, also it has supervise responsibilities, the promotes employee becomes responsible for administrative assistants and other staff.
