What is Iron iii chloride hexahydrate?
Iron iii chloride hexahydrate, also known as ferric chloride hexahydrate (FeCl₃·6H₂O, CAS 10025-77-1), is a brownish-yellow crystalline solid with a slight astringent taste. It has obvious hygroscopic and deliquescent properties, gradually turning into a reddish-brown liquid when exposed to air. FeCl₃·6H₂O dissolves extremely easily in water, with the aqueous solution showing strong acidity and the ability to coagulate proteins. It also dissolves in various organic solvents such as ethanol and acetone, but is insoluble in glycerol and phosphorus trichloride. Thanks to its good solubility and reaction activity, ferric chloride hexahydrate is widely used in water treatment, chemical industry, electronics and other fields.
