  • question_answer
    In the cell \[Zn\,\,|\,\,Z{{n}^{2+}}\,\,||\,\,C{{u}^{2+}}\,\,|\,\,Cu,\] the negative electrode is [MP PMT 1995]

    A)                 \[Cu\]  

    B)                 \[C{{u}^{2+}}\]

    C)                 \[Zn\]   

    D)                 \[Z{{n}^{2+}}\]

    Correct Answer: C

    Solution :

                    In the cell \[Zn|Z{{n}^{2+}}||C{{u}^{2+}}|Cu\]the negative electrode (anode) is Zn. In electrochemical cell representation anode is always written on left side while cathode on right side.
