Potassium chloroplatinate Chemical Properties,Uses,Production
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 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.
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 intradermal route: dermatitis. When heated to decomposition it emits toxic fumes of K2O and Cl-. Used as a catalyst for carbonylation of alkynes. See also PLATINUM COMPOUNDS.
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.]
