Q. Which one of the following reactions represents the oxidising property of $H_{2}O_{2}?$
A) $2KMnO_{4} + 3H_{2}SO_{4} + 5H_{2}O_{2} \rightarrow K_{2}SO_{4} + 2MnSO_{4} + 8H_{2}O + 5O_{2}$
B) $2K_{3}\left\lbrack Fe(CN)_{6} \right\rbrack + 2KOH + H_{2}O_{2}\ \rightarrow 2K_{4}\left\lbrack Fe(CN)_{6} \right\rbrack + 2H_{2}O + O_{2}$
C) $Pb_{2} + H_{2}O_{2} \rightarrow PbO + H_{2}O + O_{2}$
D) $2KI + H_{2}SO_{4} + \ H_{2}O_{2} \rightarrow K_{2}SO_{4} + I_{2} + \ 2H_{2}O$
Explanation
(d)
The reaction in which $H_{2}O_{2}$ is reduced while the other reactant is oxidised, represents the oxidising property of $H_{2}O_{2}.$
