Answer

On adding 5% alkaline potassium permanganate solution drop by drop to some warm ethanol, we would observe that the purple color of potassium permanganate starts disappearing; the product formed by this process; ethanoic acid can turn blue litmus red.

$\text{CH}_3\text{CH}_2\text{OH}+2[\text{O}]\xrightarrow[{\text{or}\ \text{acidified}\text{K}_2\text{Cr}_2}\text{O}_7]{{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Alkaline}\text{KmnO}_4;\text{Heat}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }\text{CH}_3\text{COOH}+\text{H}_2\text{O}$
