Question

What should be the difference in boiling points for liquids separated by fractional distillation?

Answer 1

Answer:

Fractional distillation works because the different liquids have different boiling points. When the mixture is heated: ... vapours condense when they reach a part of the column that is below the temperature of their boiling point. the liquid flows out of the column.

Answer 2

Answer:

Fractional distillation is the process of separation of a mixture of two or more miscible liquids having very close boiling points (differing less than 25°C). Fractionating columns are used for distillation in this technique.
