Chemical Properties

orange to brown lumps

Uses

Catalysis, electroplating, photography, platinum mirrors, printing for etching of zinc, producing fine color in glass and porcelain, indelible ink, microscopy.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 followed 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. In addition to this, it is also used as an analytical reagent.

General Description

Chloroplatinic acid hydrate is the most readily available compound of platinum. It may be prepared by dissolving platinum in aqua regia. Thermogravimetric analysis of this compound has been reported. The analysis shows the loss of water followed by formation of platinum tetrachloride (PtCl₄) at 220 °C and β-PtCl₂ at 350 °C finally decomposing to platinum metal at 500 °C.
