Iron(II) chloride

Iron(II) chloride is used in the synthesis of iron complexes like iron(II) hydroxide. It acts as a precursor to hydrated iron(III) oxides that are magnetic pigments. It serves as a reducing agent in organic synthesis. Also, used as a reducing flocculating agent in wastewater treatment, especially for wastes containing chromate. It is used as an intermediate, in pigments, processing aids and in solids separation agents.
