During the titration of oxalic acid againts `KMnO_(4)` , the auto catalyst used is

A

`Mn^(2+)`

B

`H^(+)`

C

`CO_(2)`

D

`MnO_(4)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
A
`2KMnO_(4)+5(COOH)_(2)+3H_(2)SO_(4)rarr2MnSO_(4)+K_(2)SO_(4)+8H_(2)O+10CO_(2)`
The reaction is catalyzed by `Mn^(2+)` ions.
