Question

Define Azeotropes? What are maximum and minimum boiling azeotropes ? Explain with example.

Answer 1

: a liquid mixture that is characterized by a constant minimum or maximum boiling point which is lower or higher than that of any of the components and that distills without change in composition. 

Answer 2

${\huge{\mathrm{\underline{\red{Azeotopes:-}}}}}$

→These are binary mixtures having same composition in liquid and vapour phase and boil at constant temperature.

‡Types of Azeotopes—

†1) Minimum boiling azeotope -

• The solution which show a large positive deviation from Raoult's law from minimum boiling azeotrope at a specific composition.

†2) Maximum Boiling azeotope -

• The solution which show a large negative deviation from Raoult's law from maximum boiling azeotrope at a specific composition.
