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.
(N/A) The chemical reaction for the thermal decomposition of ferrous sulphate is:
$2FeSO_4(s) \xrightarrow{\text{Heat}} Fe_2O_3(s) + SO_2(g) + SO_3(g)$
In this reaction,green ferrous sulphate crystals lose water on heating and then decompose to form ferric oxide,sulphur dioxide,and sulphur trioxide. The gas evolved $(SO_2)$ has the characteristic smell of burning sulphur. Since a single reactant breaks down into multiple products upon heating,it is classified as a thermal decomposition reaction.
$2FeSO_4(s) \xrightarrow{\text{Heat}} Fe_2O_3(s) + SO_2(g) + SO_3(g)$
In this reaction,green ferrous sulphate crystals lose water on heating and then decompose to form ferric oxide,sulphur dioxide,and sulphur trioxide. The gas evolved $(SO_2)$ has the characteristic smell of burning sulphur. Since a single reactant breaks down into multiple products upon heating,it is classified as a thermal decomposition reaction.
