    Which of the following occurs at anode?

    A) Reduction          

    B) Oxidation           

    C)        Both (a) and (b) 

    D)        None of these

    Correct Answer: B

    Solution :

    After ionization anion moves towards electrode such electrode is called anode. These negative ions on loosing electrons get oxidized. \[eg,\]  \[NaClN{{a}^{+}}+C{{l}^{-}}\] At cathode\[N{{a}^{+}}+{{e}^{-}}\xrightarrow{{}}Na\] At anode\[C{{l}^{-}}\xrightarrow{{}}\frac{1}{2}C{{l}_{2}}+{{e}^{-}}\]
