The number of moles of `KMnO_(4)` required to oxidise `1 mol` of `Fe(C_(2)O_(4))` in acidic medium is

A

0.6

B

1.67

C

0.2

D

0.4

Text Solution

Verified by Experts

The correct Answer is:
A

Ferrous oxalate
`{:(COO^(-)),(|),(COO^(-)):}Fe^(2+)rarrFe^(3+)+2CO_(2)+3e^(-)+7`
Thus, 5 moles of ferrous oxalate requires `KMnO_(4)=3` moles
Therefore, 1 mole of ferrous oxalate requires `KMnO_(4)=3//5 = 0.6` mole.
