The number of mole of `KMnO_(4)` that will be needed to react completely with one mole of ferrous oxalate in acidic solution is:

A

`3//5`

B

`2//5`

C

`4//5`

D

1

Text Solution

Verified by Experts

The correct Answer is:
A
`3underset(3M)MnO_(4)^(-) + 5 (Fe^(2+) underset(5M) + C_(2)O_(4)^(2-)) + 24H^(+) rarr 3 Mn^(2) + 5 Fe^(3+) + 10 O_(2) + 12 H_(2) O`
Thus `5M` of `FeC_(2)O` is oxidised by `3M` of `KMn_(2) O_(2)` the `1M` of `FeC_(2)O_(4)` is oxidised by `3//5` mole of `KMn_(2)O`.
