Custom house agent | Definition: | The clearance of goods on Import or Export‚ including unaccompanied baggage‚ involves quite a lot of procedural formalities. These formalities have to be observed by Importer / Exporter / Passenger‚ as the case may be. But in most cases the Customs station would be far away and it may not be possible for the Importer / Exporter / Passenger to attend to such work promptly. Unlike the work related to Central Excise or Income Tax‚ the Customs formalities cannot

April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much

Abstract: The purpose of this experiment was to determine the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium

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 another‚ resulting in changes in oxidation numbers of two

performing the reactions‚ you will characterize the crude reaction mixtures to determine if you formed a mix of trans enantiomers‚ the cis product‚ or a mixture of cis and trans diols. (Figure 1) In this experiment‚ you will use a common oxidizing agent‚ KMnO4. You will also use an oxidizer that you may not have discussed in lecture called Oxone ®. Oxone is a persulfate mix that reacts with acetone to produce dimethyldioxirane. Procedure: Oxone reaction Dissolve 0.40 g oxone ®
