Question 26

Ferrous sulphate decomposes with the evolution of a gas having a characteristic odour of burning sulphur. Write the chemical reaction involved and identify the type of reaction.

Answer 1

Given below is the chemical equation for the given chemical reaction:

$2{\text{FeSO}}_4\text{(s)}\stackrel{\text{Heat}}{\to }{\text{Fe}}_2{\text{O}}_3\text{(s)}+{\text{SO}}_2\text{(g)}+{\text{SO}}_3\text{(g)}$

It is a thermal decomposition reaction as one compound is breaking down into more than two products on heating.
