orange chunks or powder


Used in microanalysis to detect rubidium, cesium, and alkaloids, hydrogen tetrachloroaurate(III) trihydrate is a crucial precursor in the preparation of gold (Au). Its molecular structure involves the tetrachloroaurate(III) ion, signifying gold's +3 oxidation state, and the "H" representing the associated hydrogen ion.

General Description

Hydrogen tetrachloroaurate(III) trihydrate, commonly known as chloroauric acid, comprises the hydrogen tetrachloroaurate(III) complex ion ([AuCl₄]⁻) and three water molecules. It is a hydrated variant of chloroauric acid, a prevalent and stable gold(III) complex in aqueous solutions.
