The redox chemistry of Mn(OH){sub 2} has been studied at manganese electrodes in 0.10 M KOH solutions employing transient electrochemical techniques in an effort to elucidate mechanisms involved. The charge transfer process is shown to be affected by the film formed on the electrode surface during redox processes. The Mn(0)/Mn(II) and Mn(II)/Mn(III) pairs, which have not been reported hitherto clearly in the literature, have been observed using techniques such as chronopotentiometry and differential pulse voltammetry. Electrode potentials for these redox processes, i.e., between Mn(OH){sub 2} and higher valence oxides as well as the manganese metal, have been assigned. Diffusion coefficients of reactant molecules through the Mn(OH){sub 2} film and exchange rate constants for redox processes are also reported.
