Explanation:

A mixture of ethanol and water can easily be separated by distillation. Distillation separation technique utilizes the differences in boiling point of a mixture of two liquids.

Since water has a higher boiling point compared to alcohol, it makes it easier for the process of distillation to occur

  • In the distillation flask, the mixture is heated to a set temperature.
  • At the boiling point of alcohol, the first fraction of this component begins to rise in the mixture and it is collected over the condenser.
  • The remaining fraction will then be water.
