The electrochemical oxidation of Mn(II) has been investigated using voltammetric and in-situ spectroelectrochemical techniques. Various experimental parameters were found to exert significant effects on the process and its products. The Mn(III) or MnO{sub 4}{sup {minus}} species is produced depending on the electrode potentials, concentrations of Mn(II), voltage scan rates, and initial potentials during potential scans. These effects are discussed in terms of the equilibrium reactions between Mn(III) and MnO{sub 2} films and relative stabilities of the products. The Mn(III) is shown to be produced from an early stage of the anodic potential scan and to undergo disproportionation-conproportionation reactions depending on the concentration of each species near the electrode surface.
