Number of moles of `MnO_(4)^(-)` is required to oxidize one mole of ferrous oxalate completely in an acidic medium will be

Options

A. 0.4 moles.
B. 7.5 moles
C. 0.2 moles
D. 0.6 moles

Answer

D

Explanation

`[Fe(C_(2)O_(4))toFe^(3+)+2CO_(2)+3e^(-)]xx5` (oxidation)
`[MnO_(4)^(-)+8H^(+)+5e^(-)toMn^(2+)+4H_(2)O]` (Reduction) `xx3`
5 moles `Fe(C_(2)O_(4))-=3` moles `KMnO_(4)`
1 moles `Fe(C_(2)O_(4))-=0.6` moles `KMnO_(4)`
