    The hydrogen electrode is dipped in a solution of  \[pH=3.0\]at \[{{25}^{o}}C\]. The potential of hydrogen electrode would be

    A)  \[0.177V\]                         

    B)  \[-0.177V\]

    C)  \[0.087\text{ }V\]         

    D)  \[0.059\text{ }V\]

    Correct Answer: A

    Solution :

                    \[{{E}^{o}}=pH\times 0.059\] \[=3\times 0.059\]                 \[\therefore \]  \[{{E}^{o}}=0.177V\]
