Description and Uses

Dihydrogen hexachloroplatinate(IV) hexahydrate is used for the determination of potassium. It is also used for the purification of platinum by treating it with ammonium chloride flowed by heating of ammonium hexachloroplatinate with hydrogen yields elemental platinum. It also finds application in catalysis, electroplating, photography, platinum mirrors, printing for etching of zinc, producing fine color in glass and porcelain, indelible ink and microscopy. It is a precursor for the preparation of other platinum catalysts.
