| Chemical Properties | Potassium chloroplatinate, 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. 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. |
| Uses | Potassium chloroplatinate is a red colored crystal that issoluble in water but less soluble in alcohol. Potassium chloroplatinateis produced by a complicated treatment of thereducing of platinum chloride with sulfurous gas and addingpotassium chloride. It was used primarily in the platinumprinting process, but also for toning silver prints. |
| 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. |
| Hazard | Toxic by ingestion and inhalation. |
| Flammability and Explosibility | Not classified |
| reaction suitability | core: platinum reagent type: catalyst |
| Safety Profile | Mutation data reported.Human systemic effects by intradermalroute: dermatitis. When heated todecomposition it emits toxic fumes of K2Oand Cl-. Used as a catalyst for carbonylationof alkynes. See also PLATINUMCOMPOUNDS. |
| 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.] |
