Ferric chloride is a covalent compound. Also known as ferric chloride, it is a black powder. Melting point 306℃, boiling point 315℃, soluble in water and has a strong water absorption, can absorb water in the air and delirious. It absorbs water easily in the air and becomes crystalline ferric chloride (FeCl3?6H2O). At high temperatures it breaks down into ferrous chloride and chlorine gas. Soluble in water, ethanol, ether and acetone, slightly soluble in carbon disulfide, almost insoluble in ethyl acetate. Relative density (D25)2.90. Melting point is 282 ℃. It has a boiling point of about 316℃ and is corrosive to metals.
