Which process is commonly used to separate a mixture of ethanol and water?

Explanation:

A process in which a liquid is heated till vapors are formed and then these vapors are collected which upon cooling separates from the original mixture. This technique of separation is known as distillation.

Therefore, if we have to separate ethanol from water then due to low boiling point of ethanol it will result into vapors easily. Hence, we can separate it through distillation from water.

Hence, we can conclude that distillation process is commonly used to separate a mixture of ethanol and water.
