What is a Gold chloride (AuCl₃)?

Gold chloride (AuCl₃) is a chemical compound composed of gold and chlorine, and is one of the gold salts. It is commonly known as gold trichloride and is an important compound in gold chemistry, where gold exists in its highest oxidation state of +3. Gold chloride is highly reactive and is primarily used in the refining of gold, catalytic reactions, and chemical synthesis.

Gold chloride is soluble in water and exists in an acidic solution. It is often used in the extraction of gold from ores or gold ingots. In organic chemistry, it serves as a catalyst in various reactions. Due to its cost, it is also used in some high-value applications where gold is required. Additionally, it is used in chemical analysis as a reagent to determine the presence of gold and measure its concentration.
