Product Details

Chloroplatinic acid,CAS 16941-12-1,H2PtCl6.6(H2O),Chloroplatinic acid hexahydrate

Chloroplatinic acid or hexachloroplatinic acid is the chemical compound usually found as the hexahydrate with the formula H2PtCl6·(H2O)6. This is one of the most readily available soluble compounds of platinum. It is rarely obtained in the pure state. The commercial product is the hydronium salt of the hexachloroplatinate(IV) anion. Therefore, the correct formula is [H3O]2[PtCl6]·4H2O.The related palladium compound, [H3O]2[PdCl6], is extremely unstable and has not been isolated in pure form.
