Hydrazine reacts with thioacetamine to produce hydrogen sulfide. This reaction is first order with respect to both thioacetamide and hydrazine and is both specific and general acid catalyzed. Rapid precipitation of metal sulfides can be obtained in solutions of pH 4-6 with the thioacetamide hydrazine combination.
Rate measurements were made of the catalytic effects of copper and iron salts on the rate of the peroxydisulfate iodide reaction. The optimum conditions for the iodometric determination of peroxydisulfate have been established on the basis of these measurements.
The electroreduction of vanadium (V) and iodate investigated chronopotentiometrically with platinum electrodes subjected to a variety of pretreatment procedures. It was shown that platinization of the electrode resulting from the reduction of the platinum oxide film increases the reversibility of the electrode.
