    Number of moles of \[KMn{{O}_{4}}\]required to oxidize one mole of \[Fe({{C}_{2}}{{O}_{4}})\]in acidic medium is                  [Haryana CEE 1996]

    A)                 0.6

    B)                 0.167

    C)                 0.2

    D)                 0.4

    Correct Answer: A

    Solution :

               eq. of \[KMn{{O}_{4}}\] = eq. of \[Fe({{C}_{2}}{{O}_{4}})\]                    \[x\times 5=1\times 3\]                                 \[x=0.6\]
