Ferrous sulfate CAS 7720-78-7

Ferrous sulfate is an inorganic compound, also known as green vitriol. It appears as light green crystals and easily forms hexahydrate double salts with alkali metal sulfates (including ammonium salts), represented as M₂Fe(SO₄)₂·6H₂O, where M is an alkali metal ion or ammonium ion. The double salts of ferrous iron are much more stable; for example, ferrous ammonium sulfate (NH₄)₂Fe(SO₄)₂·6H₂O, also known as Mohr's salt, is commonly used as a reducing reagent in analytical chemistry. It is soluble in water and glycerol and exhibits certain reducing properties.
