Solution
When KMnO4 is heated with acidified oxalic acid, gas bubbles are evolved. These gas bubbles are evolved due to the formation of CO2.
Explanation:
KMnO4 reacts with oxalic acid according to the equation,
\[\ce{2MnO4- + 5C2O4^{2-} + 16H+ -> 2Mn^{2+} + 10CO2 + 8H2O}\]
Hence, bubbles evolved due to the formation of CO2 gas.
