    For which element of first transition series, the     oxidation     potential     value \[(M\to {{M}^{2+}}+2{{e}^{-}})\] is lowest?

    A)  \[Mn\]                                

    B)  \[Fe\]

    C)  \[Ni\]                                  

    D)  \[Cu\]

    Correct Answer: D

    Solution :

                    The oxidation potential value \[(M\to {{M}^{2+}}+2{{e}^{-}})\] of \[Cu\] is lowest in the given first transition series elements. \[\begin{align}   & Element\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-Mn\,\,\,\,\,\,\,Fe\,\,\,\,\,\,\,\,Ni\,\,\,\,\,\,\,\,\,Cu \\  & {{E}_{M/{{M}^{2+}}}}\,\,(in\,volt)\,\,\,\,\,-1.18\,\,\,\,\,\,0.44\,\,\,\,\,0.25\,\,\,-0.34 \\ \end{align}\]
