Write a chemical test to destinguish between us carbolic acid and alchol
Answers
Explanation:
(ii)Reaction with sodium hydrogen carbonate – Alcohol has no reaction with sodium hydrogen carbonate (NaHCO3) but in the case of Carboxylic acid it reacts with NaHCO3 which gives CH3COONa, CO2 and H2O. The reaction is evident as the carbon dioxide will turn the lime water milky
Litmus test
Take 2 ml of alcohol and carboxylic acid in a test tube, Put 1 drop of blue litmus in each test tube, the liquid which shows no effect is alcohol whereas the liquid which turns red is a carboxylic acid.
2. Sodium Bicarbonate test
Take a small amount of each compound in a test tube and add to it aqueous solution of NaHCO3. The compound which produces brisk effervescence due to the evolution of CO2must be a carboxylic acid whereas which shows no effect is alcohol.
