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.

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
