Question

How does the composition of the liquid at the top of the fractional distillation column compare with the composition of the liquid at the bottom of the column?

Answer 1

Answer:The top of the fractional distillation column will have a more volatile liquid as compared to the liquid at the bottom.

Explanation:

Fractional distillation is the method of separating liquids with different boiling points.For example,ethanol can be separated from water from a ethanol-water mixture.The component with a lower boiling point will pass in the column and collected first followed by higher boiling point component.Repeated vaporization and condensation results in the separation of the components in the mixture.
