    In the equation \[{{H}_{2}}S+2HN{{O}_{3}}\to 2{{H}_{2}}O+2N{{O}_{2}}+S\]                 The equivalent weight of hydrogen sulphide is  [BVP 2003]

    A)                 16          

    B)                 68

    C)                 34          

    D)                 17

    Correct Answer: D

    Solution :

           \[{{H}_{2}}S\to \overset{0}{\mathop{S}}\,+2e\]                                 Equivalent wt. = \[\frac{\text{Mol}\text{. wt}\text{.}}{\text{2}}\]=\[\frac{34}{2}\]=17.
