Vedclass · Answer

(A) When ferrous sulphate heptahydrate $(FeSO_4 \cdot 7H_2O)$ is heated,it first loses its water of crystallization to form anhydrous ferrous sulphate $(FeSO_4)$.On further strong heating,anhydrous ferrous sulphate decomposes to form ferric oxide $(Fe_2O_3)$,sulphur dioxide $(SO_2)$,and sulphur trioxide $(SO_3)$.The chemical equation is: $2FeSO_4(s) \xrightarrow{\Delta} Fe_2O_3(s) + SO_2(g) + SO_3(g)$.

What are the products formed when ferrous sulphate $(FeSO_4 \cdot 7H_2O)$ is heated strongly?
