Q. In the reaction, $2FeSO_4+H_2SO_4+H_2O_2 \rightarrow Fe_2(SO_4)_3+2H_2O$ , the oxidizing agent is

KCETKCET 2013Hydrogen

Solution:

Hydrogen peroxide is a powerful oxidant in acids as well as alkaline medium. It oxidises acidified ferrows sulphate to ferric sulphate.

$\underset{\text { Ferrous sulphate }}{2 FeSO _{4}}+ H _{2} SO _{4}+ H _{2} O _{2} \longrightarrow \underset{\text{Ferric sulphate}}{Fe _{2}\left( SO _{4}\right)_{3}}+2 H _{2} O $
