In the oxidation of manganese-(II) in potassium acetate supporting electrolyte high current efficiencies were achieved in a wide range of current densities at the working electrode, whereas in the presence of sodium perchlorate a successful generation of manganese(III) could be performed only at low current densities. With increasing content of water in the anolyte the amount of generated manganese (III) was abruptly decreased and its stability in the solution was diminished. Procedures are given for a successful coulometric titration of reducing substances with anodically generated manganese (III); biamperometric, potentiometric and bipotentiometric methods for the location of the end-point were employed. The error of the determinations did not exceed ± 2%.
