Suggest a chemical test to distinguish between ethanol and ethanoic acid and explain the procedure. |
|
Answer» 1. Take ethanol and ethanoic acid in two different test tubes. 2. Add nearly 18 g of sodium bicarbonate (NaHCO3) to each test tube. 3. Lots and lots of bubbles and foam will be observed from the test tube containing ethanoic acid. This is due to release of CO2 . NaHCO3 + CH3 COOH → CH3 COONa + H2O + CO2 4. Ethanol will not react with sodium bicarbonate and thus we won’t observe any change in the test tube containing ethanol. Thus we can separate ethanol from ethanoic acid. |
