What is a Gold chloroauric acid (AuCl₄H)?

Gold chloroauric acid (AuCl₄H) is a compound consisting of gold, chlorine, and a hydroxyl group (H), and is one of the gold salts in the +3 oxidation state of gold. It is primarily formed during the refining process of gold and is highly reactive. Gold chloroauric acid plays an important role as an intermediate compound in the extraction of gold from ores and refining processes. This acid is soluble in water and exists in an acidic solution. It is used in the refining of gold, where it helps dissolve gold from ores and later reduces the gold back to its pure form. Additionally, gold chloroauric acid is utilized in organic gold chemistry and other chemical reactions, serving as a catalyst or precursor in various reactions.

Due to its use of valuable gold, proper handling is essential, and it is often employed in research and industrial applications, contributing to the synthesis of gold-containing compounds and the development of novel chemical reactions.
