    Standard reduction potentials for,\[L{{i}^{+}}/Li;\] \[Z{{n}^{2+}}/Zn;\]\[{{H}^{+}}/{{H}_{2}}\]and \[A{{g}^{+}}/Ag\] are  \[-3.05,\] \[-0.762,\] \[0.00\]  and \[+0.80\]V respectively. Which of the following has highest reducing capacity?

    A)  \[Ag\]                                 

    B)  \[{{H}_{2}}\]

    C)  \[Zn\]                                  

    D)  \[Li\]

    Correct Answer: D

    Solution :

                    More negative is the value of standard reduction potential, higher will be the reducing power. \[\therefore \] \[L{{i}^{2+}}/Li\] has the highest reducing power.
