Iron (II) hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH) 2. It is produced when iron (II) salts, from a compound such as iron(II) sulfate, are treated with hydroxide ions. Iron(II) hydroxide is a white solid, but even traces of oxygen impart a greenish tinge.

Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known. The hydrated form is used medically to treat or prevent iron deficiency, and also for industrial applications.
Iron(II) fluoride or ferrous fluoride is an inorganic compound with the molecular formula FeF 2. It forms a tetrahydrate FeF 2 ·4H 2 O that is often referred to by the same names. The anhydrous and hydrated forms are white crystalline solids.
