Abstract

Conditions were found under which manganese(III) acetate can be electrochemically generated at a platinum anode with 100% current efficiency. It was found that even traces of {A table is presented} water decrease the current efficiency of the generation. The observed fact (10) that small amounts of water do not interfere in direct coulometric titrations of some substances can be explained by direct anodic oxidation of substances to be determined. The possibility of a direct coulometric titration of hydroquinone with manganese(III) acetate and an indirect coulometric determination of an unconsumed excess of manganese(III) acetate via its reaction with hydroquinone was further verified. It was confirmed that under the given conditions, the coulometrically prepared reagent is sufficiently stable even for indirect determinations.
