In addition to the anhydrous material, ferric chloride forms four hydrates. All forms of iron(III) chloride feature two or more chlorides as ligands, and three hydrates feature FeCl₄

Ferrous chloride is used in metallurgy as an electrolytic agent and as a mordant in dyeing. It has been used in the synthesis of pentasubstituted acylferrocenes. In biological research, ferrous chloride is used as a source of Fe2+ ion.Ferrous chloride is used in metallurgy as an electrolytic agent and as a mordant in dyeing.

Iron(III) chloride is the inorganic compound with the formula (FeCl3). Also called ferricchloride.The anhydrous compound is a crystalline solid with a melting point of 307.6 °C. The color depends on the viewing angle: by reflected light the crystals appear dark green.
