how will you separate a mixture of alcohol and water(difference in their boiling point is less than 20 C)
Answers
Answer:
We can separate a mixture of alcohol and water (difference in their boiling point is less than 20°C) by the process of fractional distillation.
Explanation:
Separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column is called fractional distillation. In other words, separation process in which the volatile components (having different boiling points) and the difference is less than 25°C of a mixture (such as alcohol and water) are split from one another by heating the mixture in a column and collecting and condensing the vapours drawn from different levels of the column.
The alcohol has a smaller boiling point than water. Water has a boiling point of 100°C and Alcohol has a boiling point of 78.7°C. Heat the mixture and the first to evaporate is alcohol. It will cool and condense to form a liquid. It would be collected in a beaker. The same thing will be done with the water. Both chemicals are now separated from their mixture.
