    In a reaction the ferrous \[(F{{e}^{++}})\] iron is oxidised to ferric \[(F{{e}^{+++}})\] ion. The equivalent weight of the ion in the above reaction is equal to

    A) Half of the atomic weight

    B) 1/5 of the atomic weight

    C) The atomic weight

    D) Twice the atomic weight

    Correct Answer: C

    Solution :

    The atomic weight \[Equivalent\text{ }weight\,\,=\,\,\frac{Atomic\,\,weight}{No.\,of\,{{e}^{-}}\,lost\,\,or\,\,gained}\] \[F{{e}^{2+}}\to \,\,F{{e}^{3+}}+{{e}^{-}}\]
