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

`(2)/(5)`

B

`(3)/(5)`

C

`(4)/(5)`

D

1

Text Solution

Verified by Experts

The correct Answer is:
B
The balanced redox reaction is :
`3MnO_(4)^(-) + 5FeC_(2)O_(4) + 24H^(+) rarr 3Mn^(2+) + 5Fe^(3+) + 10CO_(2) + 12H_(2)O`
`because` 5 moles of `FeC_(2)O_(4)` require 3 moles of `KMnO_(4)`
`:.` 1 moles of `FeC_(2)O_(4)` will require `(3)/(5)` mole of `KMnO_(4)`.
