Hexachloroiridic acid is an inorganic chemical compound belonging to the group of acids .

Extraction and presentation

Hexachloroiridic acid can be obtained by reacting a solution of ammonium hexachloroiridate with chlorine .

It can also be obtained by dissolving ammonium hexachloroiridate (IV) in aqua regia and then heating it.

properties

Hexachloroiridic acid is a black solid. It is in the form of long reddish-black needles that are easily soluble in water and alcohol with a reddish-brown color.

use

Hexachloroiridic acid catalyzes the electrochemical synthesis of polyaniline on the surface of base metal electrodes. It is used in the formation of iridium-substituted Dawson and Keggin-type polyoxometalates by replenishing the vacancy of the Lacunary precursors.
