The number of moles of `KMnO_(4)` required to oxidise `1 mol` of `Fe(C_(2)O_(4))` in acidic medium is

Options

A. `3//5`
B. `5//3`
C. `2//5`
D. `1//5`

Answer

A

Explanation

`{:(Fe^(2+)rarrFe^(3+)+e),((C^(3+))_(2)rarr2C^(4+)+2e),(bar(FeC_(2)O_(4)rarrFe^(3+)+2CO_(2)+3exx5)),(5e+Mn^(7+)rarrMn^(2+)xx3):}`
`:. 5` mole of `FeC_(2)O_(4)` are oxidised by `3` mole of `KMnO_(4)`.
