The hydrolysis of K2PtCl4 in water, 0.17 M NaCl and 0.08:M KBr was stu
died at room temperature using adsorption chromatography on cellulose
thin layers, ion exchange chromatography on DEAE cellulose thin layers
and paper electrophoresis. Two hydrolysis species could be separated
in solutions aged in water or dilute NaCl. In dilute KBr mixed bromoch
loroplatinates are formed.
