Activity Name: Esterification reaction in Carbon And Its Compounds
This experiment demonstrates the esterification reaction between ethanol and glacial acetic acid in the presence of concentrated sulfuric acid. The reaction produces ethyl acetate, which is an ester with a sweet smell.
- 1 ml of ethanol (absolute alcohol)
- 1 ml of glacial acetic acid
- Few drops of concentrated sulfuric acid
- Water-bath or a beaker containing water
- Test tube
- Beaker containing 20-50 ml of water
Step by Step Procedure:
- Take 1 ml of ethanol and 1 ml of glacial acetic acid in a test tube.
- Add a few drops of concentrated sulfuric acid to the test tube.
- Warm the test tube in a water-bath or a beaker containing water for at least five minutes.
- Pour the warm contents of the test tube into a beaker containing 20-50 ml of water.
- Observe the odor of the resulting mixture.
- The resulting mixture will have a sweet odor, which is characteristic of ethyl acetate, an ester.
- Handle concentrated sulfuric acid with care, as it is a corrosive and dangerous substance.
- Perform the experiment in a well-ventilated area to avoid inhaling any harmful vapors.
- Be cautious while handling the hot test tube to prevent burns or accidents.
Lesson Learnt from Experiment:
This experiment demonstrates the esterification reaction, where an alcohol (ethanol) reacts with a carboxylic acid (glacial acetic acid) in the presence of a catalyst (concentrated sulfuric acid) to form an ester (ethyl acetate). Esterification is an essential chemical reaction used to produce various esters, which are commonly found in many natural and synthetic fragrances, flavors, and other organic compounds.
