  • Oxidation reaction of MII , catalysed by Ag+, has been studied, the kinetics being followed by means of a Klelt-Summerson photoelectric colorimeter. The reaction is unimolecalar with respect to the persulphate ion and zero-molecular with respect to the manganous ion; the reaction rate is directly proportional to the silver ion concentration. The velocity constants are of the same order as found for other persulphate oxidation reactions, catalysed by the univalent silver ion. All these facts point to the similar mechanism of the reaction. The reaction is likely to be complicated under different conditions due to the occurrence of simultaneous reactions, viz., decomposition of the persulphate catalysed by the silver ion, formation of hydrogen peroxide from persulphate and sulphuric acid, and the interaction of Mn2(SO4)3 and H2O2.
