Solution

a) The colour of ferrous sulphate is green. It changes to brown after heating.

On heating: $F e S O_{4} .7 H_{2} O \to F e S O_{4} (s) + 7 H_{2} O (g)$

b) The product formed is ferric oxide ( $F e_{2} O_{3}$ ). This is a decomposition reaction.

On strong heating: $2 F e S O_{4} (s) \to F e_{2} O_{3} (s) + S O_{2} (g) + S O_{3} (g)$
