Iron(II) sulfate ( British English: iron(II) sulphate) or ferrous sulfate are salts with the formula Fe SOxHO. These compounds exist most commonly as the heptahydrate (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. Known since ancient times as copperas and as green vitriol, the blue-green heptahydrate is the most common form of this material. All iron sulfates dissolve in water to give the same aquo complex [Fe(HO)], which has octahedral molecular geometry and is paramagnetic.
Iron sulfate may refer to:
- Ferrous sulfate, Iron(II) sulfate, FeSO
- Ferric sulfate, Iron(III) sulfate, Fe(SO)
Iron(III) sulfate (or ferric sulfate), is the chemical compound with the formula Fe(SO), the sulfate of trivalent iron. Usually yellow, it is a rhombic crystalline salt and soluble in water at room temperature. It is used in dyeing as a mordant, and as a coagulant for industrial wastes. It is also used in pigments, and in pickling baths for aluminum and steel. Medically it is used as an astringent and styptic.

They react with the green vitriol, which in Grantville is called iron sulfate, to form the dark iron tannate and gallate.
For example, when a spy writes in iron sulfate, nothing will be visible until it is painted over with a solution of potassium cyanate, when the two chemicals will combine to form ferric ferrocyanide, or Prussian blue, a particularly lovely hue.
Though he preferred lampblack as a personal matter when he was replicating ancient manuscripts, the stubborn client had insisted on the ancient combination of iron sulfate and ashes of oak gall.
