    In the disproportionation reaction \[3HCl{{O}_{3}}\xrightarrow{{}}HCl{{O}_{4}}+C{{l}_{2}}+2{{O}_{2}}+{{H}_{2}}O,\] the equivalent mass of the oxidizing agent is (molar mass of \[HCl{{O}_{3}}=84.45\])   

    A) 16.89               

    B) 32.22

    C) 84.45               

    D) 28.15

    Correct Answer: A

    Solution :

    [a]  \[\begin{align}   & ClO_{3}^{-}\xrightarrow{{}}Cl_{2}^{0} \\  & x-6=-1\begin{matrix}    {} & x=0  \\ \end{matrix} \\  & \begin{matrix}    x=+5 & \begin{matrix}    {} & x=0\left( x=\text{ }oxidation\text{ }number \right)  \\ \end{matrix}  \\ \end{matrix} \\ \end{align}\] \[Equivalent\text{ }mass=\frac{Molecular\text{ }mass}{Oxidation\text{ }number}\] \[=\frac{84.45}{5}=16.89\]
