open-in-new
<p>Gold(III) chloride, traditionally called auric chloride, is an <a href="/facts/Inorganic_compound/TfFfzxSz">inorganic compound</a> of <a href="/facts/Gold/1znknojp">gold</a> and <a href="/facts/Chlorine/y27UwYBM">chlorine</a> with the <a href="/facts/Molecular_formula/hghUtthl">molecular formula</a> Au2<a href="/facts/Chloride/m9NUaUDR">Cl</a>6. The "III" in the name indicates that the gold has an <a href="/facts/Oxidation_state/W53W6s6V">oxidation state</a> of +3, typical for many gold compounds. It has two forms, the monohydrate (AuCl3·H2O) and the anhydrous form, which are both <a href="/facts/Hygroscopic/1NBGewXv">hygroscopic</a> and light-sensitive solids. This compound is a <a href="/facts/Dimer_(chemistry)/mU64PnEq">dimer</a> of AuCl3. This compound has a few uses, such as an oxidizing agent and for <a href="/facts/Catalysis/LPBS7TQC">catalyzing</a> various <a href="/facts/Organic_chemistry/djxhxaNg">organic reactions</a>. </p>
