    During electrolysis of NaCl solution, part of the reaction is\[N{{a}^{+}}\,+\,\,{{e}^{-}}\,\,\to \,\,Na\]. This is termed as

    A) oxidation                      

    B) reduction

    C) deposition                     

    D) cathode reaction

    Correct Answer: B

    Solution :

    \[{{\underset{+1}{\mathop{Na}}\,}^{+}}+{{e}^{\,-}}\,\,\xrightarrow[reduction]{}~\,\,\underset{0}{\mathop{Na}}\,,~\] means oxidation number is decreased so the reaction is reduction.
