Dissolution kinetics of manganese(III, IV) oxides in sulfuric acid in the presence of ethylenediaminetetraacetic acid was studied at various pH values and temperatures. Kinetic, spectrophotometric, and electrochemical studies demonstrated that the dissolution rate of manganese oxides is governed by the potential step at the oxide/electrolyte interface and by the solution pH. A mechanism of the dissolution is suggested
