Preparation of Bromotriphenylmethane Abstract The structure of a major component of star anise oil was derived by analyzing its IR spectroscopy melting point of after oxidation and purification. From the evidence obtained‚ it was concluded that the exact structured should be p-methoxybenzoic acid. Introduction The purpose of this experiment is to determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This

Purpose: To find number of moles of Fe+3 which react with one mole of NH3OH+ in order to partially balance the equation: NH3OH+ + 2Fe+3 "" ? + 2Fe+2 and to find the missing product. Procedure: H2C2O4 and H2SO4 were titrated with potassium permanganate. The molarity of the permanganate was then found because the molarity of the H2C2O4 and H2SO4 were already known. Then hydroxylammonium chloride and ferric sulfate and water was titrated with known potassium permanganate to get the molarity of the

The changes taking place in the metal container industry at the time of the Crown‚ Cork and Seal case using Porter’s 5 forces can be described as follows: Current Players There was a high concentration of market share held by five companies in the metal can industry. Collectively‚ the five companies held 61% of the market‚ with the remaining 39% shared by approximately 100 firms. With the five firms holding a large market share‚ the competitive environment becomes more like a monopoly and therefore

Title: Spectrophotometric analysis of a two-component mixture Aim: i. To prepare working standards of dichromate and permanganate ii. To measure the absorbance of the prepared working standards of dichromate and permanganate using a spectrophototometer iii. To determine the concentrations of permanganate in a mixture of unknown. Abstract: Working standards of dichromate and permanganate were prepared and absorbance for each found. This was done in order to plot

1. Prepare an industry analysis using Porter’s 5 Forces model. What are the key determinants of Vershire’s aluminium can profitability? Explain. (20%) * Barriers to entry I would suggest that the barriers to entry are relatively high in this industry. Although there would not be huge capital requirement to enter into the aluminum cans producing business and customer-switching costs are considered to be low‚ the fact is that the competition in this industry is very intense. There are already

Results and Discussion Potassium permanganate‚ KMnO4‚ is widely used as an oxidizing agent in volumetric analysis. In acid solution‚ MnO4- ion undergoes reduction to Mn2+ ion as shown in the equation: 8 H+(aq) + MnO4-(aq) + 5e- → Mn2+(aq) + 4 H2O(l). Since the MnO4- ion is violet and the Mn2+ ion is nearly colorless‚ the end point in titrations using MnO4- as the titrant can be taken as the first permanent pink color that appears in the solution being titrated.1 The number of moles of potassium

Aim To prepare a standard iron (II) solution To determine the concentration of potassium permanganate solution Instructions Preparation of Standard Iron (II) Solution 8g of hydrated iron (II) ammonium sulfate is weighed accurately using a 50mL beaker. The salt is transferred to a 250mL volumetric flask using a filter funnel‚ washed down with distilled water. The container is rinsed carefully and the rinsing is added to the volumetric flask. 100mL of water is added slowly to the volumetric

Introduction: Cholesterol in pork‚ sugar in a soda‚ carbohydrates in a cup of rice and alcohol in liquor. People always want to know the exact amount of things. Which is why weighing balances are devised‚ mathematical formulas and different techniques are created. In chemical analysis‚ the amount of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has

On what I have seen‚ the first experiment showed chemical reaction to be more specific‚ combustion. In the experiment the Potassium permanganate (KmnO4) was used as the oxidant‚ and obviously oil as the fuel. As the two were mixed they needed to release energy in form of heat‚ that’s where combustion occurs. I learn that Combustion is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of
