ferrous sulfate

n. A white to blue-green crystalline compound, FeSO₄, occurring in nature as various hydrate minerals such as copperas, and used as a pigment, fertilizer, and feed additive, in sewage and water treatment, and as a medicine in the treatment of iron deficiency.

fer′rous sul′fate

n. a bluish green solid, FeSO₄∙7H₂O, used in the manufacture of other iron salts, in sewage treatment and fertilizers, and in the treatment of anemia. Also called copperas . [1860–65]

ferrous sulfate

iron (II) sulfate,

chemical compound, FeSO₄. It is known as the monohydrate, FeSO₄·H₂O; the tetrahydrate, FeSO₄·4H₂O; the pentahydrate, FeSO₄·5H₂O; and the heptahydrate, FeSO₄·7H₂O. The heptahydrate is also called green vitriol, copperas, or melanterite (a mineral that commonly occurs with pyrite). It is a blue-green monoclinic crystalline water-soluble salt. It is prepared commercially by oxidation of pyrite (iron sulfide) or by treating iron with sulfuric acid. It is used in the manufacture of inks, in wool dyeing as a mordant, and in water purification as a substitute for aluminum sulfate. It melts at 64&degC;, and at 90&degC; it loses water of hydration to form the monohydrate, a white, monoclinic, crystalline powder that occurs naturally as the mineral szomolnokite. The mineral siderotil is iron sulfate pentahydrate.

[′fer·əs ′səl‚fāt] (inorganic chemistry) FeSO₄·7H₂O Blue-green, water-soluble, monoclinic crystals; used as a mordant in dyeing wool, in the manufacture of ink, and as a disinfectant. Also known as copperas; ferrisulphas; green copperas; green vitriol; iron sulfate.
