The chemical formula for gold chloride is AuCl3. It consists of one atom of gold (Au) and three atoms of chlorine (Cl), which are covalently bonded together in a molecule. The compound has a yellowish-brown color and is highly soluble in water. Gold chloride is commonly used in the production of gold nanoparticles and as a catalyst in various chemical reactions. When heated, it can decompose into its constituent elements, releasing chlorine gas and leaving behind metallic gold.
