Question

what type of odour is observed on heating ferrous sulphate crystals​

Answer 1

Explanation:

The color of ferrous sulphate crystals is green. Ferrous sulphate crystals contain water molecules (FeSO4. ... On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3). So, the gas emitted smells like burning sulphur.

Answer 2

The odour is characteristic odour of burning sulphur.

Explanation:

Ferrous sulphate undergoes decomposition, that is it breaks into two or more than two products on absorption of energy. Two gases are evolved namely sulphur dioxide  and sulphur trioxide  and a solid ferric oxide  which remains as such and is called as residue.

The balanced chemical reaction is as follows:

$2FeSO_4(s)\rightarrow Fe_2O_3(s)+SO_2(g)+SO_3(g)$
