How many mole of H(2)C(2)O(4) oxidized s...

How many mole of `H_(2)C_(2)O_(4)` oxidized separately by one mole of `KMnO_(4)` in acid medium.

A

8 mole

B

2 mole

C

`(5)/(2)` mole

D

3 mole

Text Solution

Verified by Experts

The correct Answer is:
C
Oxidaiton half `C_(2)O_(4)^(2-)to2CO_(3)+2e^(-)`
Reduction half `:MnO_(4)^(-)+5e^(-)toMn^(2+)`
Hence, `(5)/(2)` mole of Oxalic acid will be oxidised by 1 mole of `KMnO_(4)`.
