What happen when Ferrous Sulphate crystals are heated???????????
Also write a balanced equation for it
FeSO4(s) ----------> Fe2O3(s) + SO2(g) + SO3(g)
Ferrous sulphate is green in colour. On heating, the green crystals are converted into a dirty-yellow anhydrous solid as it loses water of crystallization. When further heated, the anhydrous material releases sulphur dioxide and sulphur trioxide leaving a reddish-brown iron oxide.
2 FeSO4 → Fe2O3 + SO2 + SO3
