Summary
Conditions for the anodic generation of cobalt(III) acetate with high current efficiency in non-aqueous solutions of potassium acetate in acetic acid have been investigated. The presence of water or acetic anhydride in the anolyte diminishes the amount of the generated oxidant. The stability of the generated cobalt(III) acetate solution is decreased in the presence of water and at elevated temperatures. Procedures for coulometric titrations of reducing substances with cobalt(III) acetate, using the biamperometric or the potentiometric end point detection, are described.
