Gold (III) chloride, traditionally called auric chloride, is one of the most common compounds of gold. It has the formula Au Cl 3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is the most stable form for gold in its compounds. Gold also forms another chloride, gold (I) chloride (AuCl), which is less
