Iron (II) sulfate ( British English: iron (II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 · x H 2 O. These compounds exist most commonly as the hepta hydrate ( x = 7) but are known for several values of x. The hydrated form is used medically to treat iron deficiency, and also for industrial applications.
