Ferrous Chloride Tetrahydrate
Iron(II) chloride tetrahydrate is used as a reducing agent in metallurgy, in pharmaceutical preparations, as a mordant in dyeing and in sewage treatment. Ferrous chloride has a kind of niche application. During the laboratory synthesis of iron complexes, ferrous chloride acts as a reducing flocculating agent in waste water treatment, particularly for wastes containing chromate. It is the precursor to hydrated iron(III) oxides that are magnetic pigments. Ferrous chloride is employed as a reducing agent in many organic synthesis reactions.
Analytical reagent, wastewater treatment, reducing agent, mordant in dyeing, pharmaceutical, metallurgy and photography field.
Property: blue-green crystal; deliquesce; soluble in water, alcohol and acetic acid, lightly soluble in aceto ne and insoluble in ether.
