Potassium hexachloroplatinate, an inorganic compound, is an example of a comparatively insoluble potassium salt.
The precipitation of this compound from solutions of hexachloroplatinic acid was formerly used for the determination of potassium by gravimetric analysis.[2]
Potassium hexachloroplatinate may be reduced by hydrazine dihydrochloride to give the corresponding tetrachloroplatinate salt.[3]
