    Which of the following statements is true for electrochemical Daneil cell?

    A) Electrons flow from copper electrode to zinc electrode

    B) Current flows from zinc electrode to cop- per electrode

    C) Cations move towards copper electrode

    D) Cations move towards zinc electrode

    Correct Answer: C

    Solution :

    [c] Cations more towards copper electrode \[As\,C{{u}^{2+}}\]ions gain electrons and are deposited on copper. In electrochemical Daniel cell, \[Zn\left| Z{{n}^{2+}}({{C}_{1}})\left\| C{{u}^{2+}}({{C}_{2}})\left| Cu \right. \right. \right.\] i.e by convention, left hand side is oxidation and right hand side reduction takes place.
