How many moles of KMnO(4) are needed to ...

How many moles of `KMnO_(4)` are needed to oxidise a mixture of 1 mole of each `FeSO_(4) & FeC_(2)O_(4)` in acidic medium `:`

A

`4//5`

B

`5//4`

C

`3//4`

D

`5//3`

Text Solution

Verified by Experts

The correct Answer is:
A
Equivalent of `KMnO_(4)`=equivalent of `FeSO_(4)+`equivalent of `FeC_(2)O_(4)`
`x xx5=1+1xx3`
`x=(4)/(5)` mole
