  • question_answer
    During electrolysis of \[NaCl\]solution, part of the reaction is \[N{{a}^{+}}+{{e}^{-}}\to Na.\] This is termed as    [NCERT 1984]

    A)                 Oxidation           

    B)                 Reduction

    C)                 Deposition         

    D)                 Cathode reaction

    Correct Answer: B

    Solution :

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