    How would you distinguish experimentally between an alchohol and a carboxylic acid ?

    Asked By Lexi Cameron


    • (1) Acid test : Reaction with carbonates/hydrogen carbonates. Take samples of alcohol and carboxylic acid in two test tubes, and add sodium carbonates or sodium bicarbonate solution to each. The compound which will produce brisk effervescence of CO2 gas will be acid.(2) Alcohal test : Take small amount of ethanol and ethanoic acid in test tube A and B.Add 5% solution of alkaline potassium permanganate drop by drop to this solution and warm the test tube.The color of potassium will disappear in test tube containing alcohol.
