This involves redox reaction. Oxalic acid is oxidised to CO2 by KMnO4 (Mn7+) which itself gets reduced to Mn2+. The reaction may takes place in acidic medium or basic medium.
In acidic medium the net balanced equation is-
2MnO4−+ 5H2C2O4 + 6H+ ⟶ 2Mn2+ + 10CO2 + 8H2O
In Basic medium-
2MnO4−+ 3H2C2O4 + H2O + 8OH- ⟶ 2OH- + 2MnO2 + 6CO2 + 11H2O
Balancing of ions is given below-
