Description and Uses
Green vitriol (FeSO₄·7H₂O) has been known since the thirteenth century; it crystallizes from solutions of iron or iron bases in dilute sulfuric acid. The heptahydrate forms green monoclinic crystals with a density of 1.88 and is very soluble in water (296 g L⁻¹ FeSO₄ at 25 °C). The white monohydrate is obtained by precipitating the aqueous solution with ethanol, heating the heptahydrate to 140 °C in vacuo, or crystallizing it from 50% sulfuric acid. This can be further dehydrated to white, amorphous FeSO₄ by heating to 300 °C in a stream of hydrogen. At red heat, the sulfate decomposes:
2FeSO₄ → Fe₂O₃ + SO₂ + SO₃
A tetrahydrate (FeSO₄·4H₂O) crystallizes from aqueous solutions above 56 °C.
