When a solution of ethyl alcohol and alkaline KMnO4 is heated the pink colour of the solution disappears. Since, KMnO4 is a strong oxidising agent it oxidises ethanol to ethanoic acid by donating nascent oxygen. If excess of KMnO4 is added the the purple color will persist.
CH3CH2OH + Alkaline KMnO4 → CH3COOH
