    In the reaction                 \[{{C}_{2}}O_{4}^{2-}+MnO_{4}^{-}+{{H}^{+}}\,\to \,M{{n}^{2+}}+C{{O}_{2}}+{{H}_{2}}O\]                 the reductant is                [EAMCET 1991]

    A)                 \[{{C}_{2}}O_{4}^{2-}\]

    B)                 \[MnO_{4}^{-}\]

    C)                 \[M{{n}^{2+}}\]               

    D)                 \[{{H}^{+}}\]

    Correct Answer: A

    Solution :

           \[{{C}_{2}}O_{4}^{2-}+MnO_{4}^{-}+{{H}^{+}}\to M{{n}^{2+}}+C{{O}_{2}}+{{H}_{2}}O\].                                 In this reaction \[{{C}_{2}}O_{4}^{2-}\] act as a reducing agent.
