Question

answer the following question

Answer 1

a) ferrous sulphate crystals on heating looses the water of crystalization so the colour of ferrous sulphate changes
b) ferrous sulphate(feso4) decomposes to form ferric oxide (fe2o3) sulphur dioxide(so2) nd sulphur trioxide(so3)

Answer 2

$2FeSO_4 \frac{heat}{--\ \textgreater \ } Fe_2O_3 + SO_2 + SO_3$

(a) On burning Ferrous sulphate crystals, it loses water and changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide.

(b) The products obtained are Ferric oxide, Sulphur dioxide and sulphur trioxide.
