How to separate an azeotropic mixture
WebAn azeotropic mixture can be separated by distillation if there is a sufficient number of theoretical plates. b. If the difference in boiling points between two liquids is large (i.e., >70 °C), a fractional distillation is unlikely to separate them completely. c. Distilling to dryness can result in explosions.

WebDistillation, the most frequently used separation method in chemi-cal processes, is based on the difference in the relative volatilities of the components of a liquid mixture [1]. PSD … Web(a) i. Ideal solution is that solution which follows Raoult's law. An ideal solution or ideal mixture is a solution in which the enthalpy of solution ( Δ H s o l u t i o n , Δ V s o l u t i o n , Δ S s o l u t i o n is 0 ,with the closer to zero the enthalpy of solution, the more "ideal" the behavior of the solution becomes ii.
