    In a reaction the ferrous \[(F{{e}^{2+}})\] iron is oxidised to ferric \[(F{{e}^{3+}})\] 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 :

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