    The emf of a galvanic cell, with electrode potential of zinc \[=+0.76V\] and that of copper \[=0.34\,\,V\], is:

    A) \[0.76\,\,V\]                      

    B) \[1.1\,\,V\]

    C) \[-1,\,\,1\,\,V\]                

    D) \[1.6\,\,V\]

    Correct Answer: B

    Solution :

    The emf of a galvanic cell =\[\begin{matrix}    electrote\,\,potential & electrode\,\,potential  \\    of\,\,zinc & -of\,\,copper  \\ \end{matrix}\]\[=0.76-(-0.34)=1.1V\]
