190-192Permanganate oxidation of thallium(I) in aqueous perchloric acid has 2:3 stoichiometry (oxidant: reductant) and manganese(IV) and thallium(III) are the products. A clean second order kinetics is followed by the reaction with fractional dependence on [acid]. The. results are explained by a mechanism involving HMnO4 as the active oxidant species
