Anhydrous ferric chloride is a covalent compound FeCl 3 that dissolves in organic solvents as well as in water. It forms bright-yellow crystals as the hexahydrate. Anhydrous ferric sulphate is colorless, but crystals of Fe 2 (SO 4 ) 3 ·9h 2 O are yellow. Ferric ammonium alum, FeNH 4 (SO 4 ) 2 ·12H 2 O is pale violet, the typical ferric color in solution. This is an "alum" without aluminium, the iron standing it for it. It is a mordant because of the gelatinous ferric hydroxide formed when a solution is make alkaline. There are also ferric potassium alum, also colorless or violet, and ferrous ammonium sulphate, which forms blue-green crystals of the hexahydrate.
