The number of moles of `KMnO_(4)` that will be required to react with one mol of ferrous oxalate is :

A

`3/5`

B

`2/5`

C

`4/5`

D

1

Text Solution

Verified by Experts

The correct Answer is:
A
`Mn^(7+) + 5e^(-) to Mn^(2+) ] xx 3`
`{:(Fe^(2+) to Fe^(3+) + e^(-)),(C_(2)O_(4)^(2-) to 2CO_(2) + 2e^(-)):}]xx 5 `
3 moles of `KMnO_(4) = 5 " moles of " FeC_(2)O_(4)`
` :. ` 1 mol of forrous oxalate ` -= 3/5" mol of " KMnO_(4)`
