Potassium chloroplatinate is a red colored crystal that is
soluble in water but less soluble in alcohol. Potassium chloroplatinate
is produced by a complicated treatment of the
reducing of platinum chloride with sulfurous gas and adding
potassium chloride. It was used primarily in the platinum
printing process, but also for toning silver prints. | [CAS DataBase Reference]

| [Chemical Properties]
Potassium chloroplatinate(16921-30-5), also known as potassium hexachloroplatinate(IV), is an inorganic compound with the formula K2PtCl6. It is an orange to yellow crystalline solid that is insoluble in water. It is formed by reaction of soluble potassium salt solution and chloroplatinic acid. This substance is synthesized by reacting a soluble potassium salt solution with chloroplatinic acid. Potassium hexachloroplatinate(IV) is used for the determination of potassium by gravimetric analysis. It is also used to prepare potassium tetrchloroplatinate by reduction using hydrazine dihydrochloride. Further, it is used in photography. | [Preparation]
It is formed by reaction of soluble potassium salt solution and chloroplatinic acid. | [General Description]
Potassium hexachloroplatinate (K2PtCl6) is a source material for the preparation of platinum based compounds. It can be used in the preparation of platinum colloids by its reduction in an aqueous solution. | [Flammability and Explosibility]
Notclassified | [Purification Methods]
It crystallises from water (20mL/g) between 100o and 0o. Its solubility in H2O is 0.7% at 0o, 1.12% at 20o, 2.16% at 50o and 5.13% at 100o. [Grube in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1571 1965.] |
