General description

Iron(II) sulfate heptahydrate is a hydrated iron(II) salt. It undergoes thermal degradation to afford hydrosulfate and oxysulfate of iron(III). Isothermal and dynamic thermal analysis methods have been proposed to study its thermal decomposition in air.

Application

Iron(II) sulfate heptahydrate (FeSO4, FeSO4.7H2O) has been used to compose the Bold′s basal medium (BBM). It has been used to evaluate the total antioxidant activity of serum.
