Abstract
The electrode kinetics at 25°C of the reduction of manganese(III) on an oxidised platinum surface confirms an unusually low transfer coefficient of 0.26. Interpretation involving a comparison with a correlation of hydrolytic constants of similar trivalent cations and their several redox potentials points to a hydroxo- or oxo-bridged transition state. The MnHi/Mn11 conditional standard electrode potential was observed to be 1.535 V at ionic strength 3.31 mol dm-3 against H2|HC1O4(3 mol dm-3), NaClO4 (0.31 mol dm-3).
