What happen when Ferrous Sulphate crystals are heated???????????

  Also write a balanced equation for it

Asked by Swati Mishra(st. michael's convent school) , on 19/9/11


Dear Student,

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
