100 " mL of " x M `KMnO_(4)` is requried oxidise 200 " mL of " 0.2 M ferric oxalate in acidic medium what is the normality of `KMnO_(4)`?

Explanation

Formula of ferric oaxalate `=overset(+3)(Fe_2)(C_2overset(2-)(O_4))_3`
`Fe^(3+)` ion does not oxidises whereas `C_2O_4^(2-)` ion is oxidises to `CO_2`.
`3C_2O_4^(2-)to6CO_2+6e^(-)(n=6)`
`5e^(-)+MnO_4^(ɵ)toMn^(2+)(n=5)`
`MnO_4^(ɵ)-=C_2O_4^(2-)`
`1mEq-=1mEq`
`N_1V_1(mL)-=N_2V_2(mL)`
`x xx5` (n-factor)`xx100mL=0.2xx6` (n-factor) `xx200mL`
`x=(0.2xx6xx200)/(5xx100)=(24)/(50)=2.4N`
