Question
Chapter 10.3, Problem 25E
Interpretation Introduction
Interpretation: The term minimum boiling azeotrope and the reason that it is impossible to separate an azeotropic mixture completely by distillation needs to be explained.
Concept introduction: The process of separation of components from a liquid mixture by the process of selective boiling and condensation. Azeotropes can be defined as a mixture of two liquids whose boiling point and composition are constant through the process of distillation.

Students have asked these similar questions
Azeotropic mixtures mix with each other in all proportions, since the composition of the liquid and vapor phases is the same. Ethyl alcohol and water in a liquid state are also an azeotropic mixture. Why?
10. For each of the following mixtures, suggest a separation technique and explain a basis for your choice:
(a) Acetone (a volatile liquid) and benzaldehyde
(b) N-Ethylpentanamine, butanamide and phenol. Explain.
Determine what could be the best solvent to differentiate anthracene and benzylamine based on their predicted solubility.
