    The standard reduction potential of \[L{{i}^{+}}/Li,B{{a}^{2+}}/Ba,N{{a}^{+}}/Na\]and \[M{{g}^{+}}/Mg\]are -3.05, -2.73, -2.71 and -2.37 volts respectively. Which one of the following is strongest oxidising agent?

    A)  \[N{{a}^{+}}\]                  

    B)  \[L{{i}^{+}}\]

    C)  \[B{{a}^{2+}}\]                                

    D)  \[M{{g}^{2+}}\]

    Correct Answer: D

    Solution :

     The strongest oxidising agent is one which has maximum tendency to gain electrons, i.e. whose \[{{\text{E}}^{\text{o}}}_{\text{Red}}\]is maximum
