Abstract
Oxidation of Mn(II) by HOCl in weakly acidic solution, in the presence of tungstate, results in the formation of the soluble heteropolyoxotungstate [MnW6O24]. The kinetics of formation of this species was studied from 15-35°C over the pH range 4.9-5.4 and found to exhibit solution autocatalytic behaviour. The oxidation kinetics was found to follow an expanded rate expression consisting of two terms:
