In aqueous solutions PtCl{sub 4}{sup 2{minus}} is oxidized by OH to PtCl{sub 4}OH{sup 2{minus}} and PtCl{sub 6}{sup 2{minus}} reduced by e{sub aq}{sup {minus}} or H to PtCl{sub 6}{sup 3{minus}}. These Pt(III) species both react subsequently with H{sub 2}O to produce PtCl{sub 4}(OH){sub 2}{sup 3{minus}} and H{sup +}. All these processes are fast, whereas decay of PtCl{sub 4}(OH){sub 2}{sup 3{minus}} by disproportionation is relatively slow. Kinetics of reactions and properties of intermediate species are described. The early stage of the reductive elimination/oxidative addition (REOA) mechanism of Pt(II) and Pt(IV) is proposed. 31 refs., 3 figs.
