Explanation:
To separate a mixture of alcohol (ethanol) and water, you can use a process known as fractional distillation. This technique relies on the fact that the compounds in the mixture have different boiling points. Since ethanol boils at a lower temperature (78.5 degrees Celsius) than water, the alcohol vaporizes while most of the water remains a liquid.

The process of separating alcohol and water is as follows :
• Take the mixture in a distillation flask
• Fit it with a thermometers.
• Arrangement of the apparatus is done as shown in the below given figure.
• Heat the mixture slowly keeping a close watch at the thermometer.
• The alcohol vapourises, condenses in the condenser and can be collected from the condenser outlet.
• Water is left behind in the distillation flask
