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

that is oxidized loses electrons or contains an atom that increases in oxidation number. Something that is reduced gains electrons or has an atom that decreases in oxidation number. An oxidizing agent is a something that oxidizes something‚ meaning that the oxidation agent is itself reduced. A reducing agent is a something that reduces something else‚ and is itself oxidized. In this experiment‚ the class studied the electrochemical nature of corrosion of iron. Corrosion is the deterioration a material

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
