iron(II) sulphate

Chemistry

An off-white solid, FeSO₄.H₂O; monoclinic; r.d. 2.970. There is also a heptahydrate, FeSO₄.7H₂O; blue-green monoclinic; r.d. 1.898; m.p. 64°C. The heptahydrate is the best known iron(II) salt and is sometimes called green vitriol or copperas. It is obtained by the action of dilute sulphuric acid on iron in a reducing atmosphere. The anhydrous compound is very hygroscopic. It decomposes at red heat to give iron(III) oxide, sulphur trioxide, and sulphur dioxide. A solution of iron(II) sulphate is gradually oxidized on exposure to air, a basic iron(III) sulphate being deposited.
