Question

Explain why functional distillation but not simple distillation is used to separate a mixture of two miscible liquid whose boiling point differ by about 25degree c

Answer 1

Answer:

Explanation:

Distillation is used for separating a mixture of miscible liquids into its components, when both the components are miscible with each other and the difference in the boiling points of the liquid components is more than 20-25 degree Celsius.

The mixture is heated in a flask until the mixture boils, the vapors produced due to boiling of liquid are passed through a condenser, where they are condensed back to the pure liquid which is collected separately

Those liquid mixtures can be separated by distillation in which difference in the boiling points of the liquid components is more than 20-25 degree Celsius.
