What is Hexachloroiridic acid hexahydrate?

Chemical properties

black crystals

The Uses of Hexachloroiridic acid hexahydrate

Hexachloro-iridate(2-) Dihydrogen is used as a catalyst for formic acid electro-oxidation

Flammability and Explosibility

Non flammable

Purification Methods

If it contains nitrogen, then repeatedly concentrate a conc HCl solution until free from nitrogen, and dry free from HCl in a vacuum over CaO until crystals are formed. The olive-green solid (yellow at ~700o) is very hygroscopic. [Woo & Yost J Am Chem Soc 53 884 1931, Grube in Handbook of Preparative Inorganic Chemistry (Ed.
