  • question_answer
    The emf of a galvanic cell, with electrode potentials of silver = +0.80V and that of copper = + 0.34 V, is [AIIMS 1999]

    A)                 ? 1.1 V 

    B)                 + 1.1 V

    C)                 + 0.46 V               

    D)                 + 0.76 V

    Correct Answer: C

    Solution :

                    \[{{E}^{o}}=E_{A{{g}^{2+}}/Ag}^{o}+E_{Cu/C{{u}^{2+}}}^{o}\]\[=-0.34+0.80=+0.46\,V\].
