Reaction Kinetics and Mechanism of Formation of [MnW6O24]8- by Hypochlorous Acid Oxidation of Mn(II)aq in the Presence of Tungstate
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:
