The precipitation of this compound from solutions of hexachloroplatinic acid was formerly used for the determination of potassium by gravimetric analysis.[4] It is also useful as an intermediate in the recovery of platinum from wastes.[5]
Using salt metathesis reactions, potassium hexachloroplatinate is converted to a variety of quaternary ammonium and related lipophilic salts. These include tetrabutylammonium salt (NBu4)2PtCl6, which has been investigated as a catalyst.[6]
Reduction of potassium hexachloroplatinate with hydrazine dihydrochloride gives the corresponding tetrachloroplatinate salt.[7][8]
Potassium hexachloroplatinate reacts with aqueous ammonia to give chloropentammineplatinum chloride:[9]
Dust containing potassium hexachloroplatinate can be highly allergenic. "Symptoms range from irritation of skin and mucous membranes to life-threatening attacks of asthma."[10]
