Question

Fractional distillation is suitable for separation of miscible liquids with a

boiling point difference of about 25K or less. What part of fractional distillation

apparatus makes it efficient and possess an advantage over a simple distillation

process. Explain​

Answer 1

Answer:

FRACTIONAL DISTILLATION OF MISCIBLE LIQUIDS

A fractionating column makes the process of fractional distillation more efficient than the process of simple distillation by providing increased possibilities for condensation of the liquid. A fractionating column packed with glass beads or glass helices provides a large surface area for the vapours to collide and lose energy so that they can be condensed and distilled quickly. Increasing the length of the fractionating column would also increase the efficiency of fractional distillation.
