How does the acidified permanganate solution react with
oxalic acid.
Write the ionic equations for the reactions.

Text Solution

Verified by Experts

Reactions of `KMnO_(4)` in acidic medium
`MnO_(4)^(-)+8H^(+)+5e^(-)rarr Mn^(2+)+4H_(2)O`
Oxalic acid : `C_(2)O_(4)^(2-) rarr 2CO_(2)+2e^(-)`
From equation (i) and (iv)
`5C_(2)O_(4)^(2-)+2MnO_(4)^(-)+16H^(+) rarr 2Mn^(2+)+8H_(2)O+10 CO_(2)`
