Name the oxidizing agent used for the conversion of ethanol to ethanoic acid. Distinguish between ethanol and ethanoic acid on the basis of
(i) litmus test
(ii) reaction with sodium hydrogen carbonate.

Alkaline potassium permanganate KMnO4 or acidified potassium dichromate K2CrOr Ethanol and ethanoic acid can be distinguished on the basis of:

(i) Litmus test: Ethanol: No colour change.
Ethanoic acid: Turns blue litmus to red

(ii) Sodium hydrogen carbonate NaHC03 test:
Ethanol acid: It does not react with NaHC03
Ethanoic acid: It reacts with NaHC03 to give rise to CH3COONa, CO2 and H2O. The gas (CO2) turns lime water milky.
