| Abstract: | The kinetics of the homogeneous oxidation of hydrogen in the Pt(II)–Pt(IV)–Cl––H2O system has been studied for the first time in conditions permitting to avoid the formation of Pt-black. It is shown that platinum (II) Pt(II)Cli(H2O)4-i, where i=1, 2, 2], is active in the reaction, whereas the PtCl
