    In the following reaction, which choice has value twice that of the equivalent mass of the oxidising agent                 \[S{{O}_{2}}+{{H}_{2}}O\xrightarrow{{}}3S+2{{H}_{2}}O\]                               [DPMT 2000]

    A)                 64          

    B)                 32

    C)                 16          

    D)                 48

    Correct Answer: B

    Solution :

               \[\underset{+4}{\mathop{S{{O}_{2}}}}\,+2{{H}_{2}}O\to \underset{0}{\mathop{S}}\,+2{{H}_{2}}{{O}_{2}}\]                                 \[EW=\frac{M}{4}=\frac{64}{4}=16\];     Twice \[16\times 2=32\]
