Fe2SO4 on heating gives Fe2O3 + SO2 +SO3
Ferrous sulphate on heating gives ferric oxide + sulphur dioxide + sulphur trioxide

On heating, ferrous sulphate crystalslose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrousferrous sulphate decomposes to formferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).
