Question

In alkaline medium $ClO_{2}$ , oxidizes $H_{2}O_{2}$ to $O_{2}$ and itself gets reduced to $Cl^{-}$ , How many moles of $H_{2}O_{2}$ are oxidised by $2$ mole of $ClO_{2}?$

Answer 1

The balanced chemical equation is:
$2ClO_{2}+5H_{2}O_{2}+2OH^{-}\overset{}{ \rightarrow }2Cl^{-}+5O_{2}+6H_{2}O$
$1molClO_{2}=2.5molH_{2}O_{2}2molClO_{2}=5molH_{2}O_{2}$
