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.
