Quantitative Analysis: % Copper in an Ore May 3‚ 2006 Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis‚ we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass. Introduction: Chemical analysis takes place under two different scenarios. In one case‚ you need to find out the chemical identity of some material. The first kind of analysis‚ in which the chemical

Redox Titration Analysis of a Commercial Bleach A. Purpose ! ! ! To review oxidation-reduction reactions and their stoichiometry. To learn the concept and technique of redox titration. To determine the percent (m/v) of an active ingredient‚ sodium hypochlorite (NaOCl)‚ in a commercial bleaching agent. B. Theoretical Background Whereas acid-base reactions involve the transfer of a proton‚ oxidation-reduction or redox reactions involve the transfer of electrons from one substance to

sites of interaction. The structure of hD3 and hD2L receptors was differentiated by means of MD simulations and D3 selective ligands were discriminated‚ in terms of binding energy‚ by docking calculation. Robust correlation of computed and experimental Ki was obtained for hD3 and hD2L receptor ligands. In conclusion‚ the present computational approach seems suitable to build and refine structure models of homologous dopamine receptors that may be of value for structure-based drug discovery of selective

Green Oxidation of Borneol to Camphor Abstract: This lab converted borneol to camphor using a green oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol

when we use different initial concentrations. We do use a catalyst in this reaction to speed up the process and lower the activation energy needed to run the reaction. The catalyst is the Iodide ion that will be used in the form of potassium iodide (KI). Results at the end of the trails will be used to compose a rate of law for the reactions. This law will show the “dependence of the rate on the concentration of both H202 and I-. The rate of reaction equation is as follows: Rate of reaction = k [H202]M
