how can we separate alcohol from water? explain the whole process with diagram
Answers
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. .

Answer:
Separating a liquid from a mixture – fractional distillation
Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points. When the mixture is heated, one liquid evaporates before the other.
