Wired Faculty App

Two liquids A and B form type II non-ideal solution which shows a minimum in its temperature -mole fraction plot (T-X diagram). Can the two liquids be completely separated by fractional distillation?

Solution

The two liquids cannot be separated completely by fractional distillation because they form a constant boiling azeotropic mixture, therefore at a definite composition both the liquids will distill over without any change in composition.
