    The oxidation potential of a hydrogen electrode at pH = 10 and \[p{{H}_{1}}=1\]                                               [JIPMER 2000]

    A)                 0.059 V

    B)                 0.59 V

    C)                 0.00 V   

    D)                 0.51 V

    Correct Answer: B

    Solution :

               \[{{E}_{OP}}=E_{OP}^{o}-\frac{0.059}{1}\log \frac{[{{H}^{+}}]}{{{P}_{{{H}_{2}}}}}\]                 \\[[{{H}^{+}}]={{10}^{-10}};\,\,{{P}_{{{H}_{2}}}}=1\,\,atm\]; \[{{E}_{OP}}=0.59\,\,V\].
