Chemical Information

FooDB Name

Iron(II) sulfate (FeSO4)

Description

Iron(II) sulfate (Br.E. iron(II) sulphate) or ferrous sulfate is the chemical compound with the formula FeSO4. 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(H2O)6]2+, which has octahedral molecular geometry and paramagnetic. Together with other iron compounds, ferrous sulfate is used to fortify foods and to treat iron-deficiency anemia.
