    Electrode potential of \[Z{{n}^{2+}}/Zn\]is -0.76 V and that of \[C{{u}^{2+}}/Cu\]is +0.34 V. The EMF of the cell constructed between these two electrodes is

    A)  1.10 V                         

    B)  0.42 V

    C)  -1.1 V                         

    D)  -0.42 V

    Correct Answer: A

    Solution :

    \[E_{cell}^{o}=E_{cathode}^{o}-E_{anode}^{o}=0.34-(-0.76)=1.10\,V.\]
