How to separate alcohol and Water

To separate alcohol from water fractional distillation technique. This technique is based on the difference in boiling points of the liquids. Alcohol and water have different boiling points. Boiling point of water is 100ºC and boiling point of alcohol is 78.7ºC. Boiling point of alcohol is less than that of water. The mixture of alcohol and water is heated and the alcohol is first evaporated due to its low boiling point. Then the vapor is allowed to condensed and cooled. The liquid obtained after this step is collected in a beaker. This liquid is the alcohol. The same procedure is repeated for water. Now both the liquids are separated. .
