Gold(III) chloride 13453-07-1-Molbase

Gold (III) chloride, traditionally called auric chloride, is a chemical compound of gold and chlorine. With the molecular formula AuCl3, the name gold trichloride is a simplification, referring to the empirical formula. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds.
