Abstract

- Dilute solutions of the square-planar tetra-aqua complex pt(H2O)42+ have been prepared in a 1.00 M perchloric acid medium by addition of excess silver(I) perchlorate to potassium tetrachloroplatinate(II), equilibration at 70°C, filtration of the silver chloride precipitate, and subsequent separation of the excess silver from the solution by electrolysis. The complex has also been prepared by addition of mercury(II) perchlorate to tetrachloroplatinate(II) solutions. The UV and visible absorption spectrum of the complex has been recorded and its hydrolysis qualitatively studied. The experiments indicate that Pt(H2O)42+ is a weak acid with pKa>2.5. A white, amphoteric hydroxide of platinum(II) is precipitated in the pH region 4 to 10.
