What are Azeotopes
  • 2 answers

Pawni Chaudhary 4 years ago

azeotrope or a constant boiling point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation. This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture

Azeotropes

  • Azeotropes are binary mixturespossessing the same synthesis in fluid, vapor stage and boiling stage at a steady temperature.
  • The components of azeotropic mixtures are separated by fractional distillation.
  • Azeotropes can be broadly categorized into two types-
  1. Minimum boiling azeotrope

The solutions showing positive deviation from Raoult’s law. For instance, solution of ethanol and water on fractional distillation results in a solution containing approximately 95% by volume of ethanol.

  1. Maximum boiling azeotrope.

The solutions showing negative deviation from Raoult’s law. For instance, solution of nitric acid and water has the approximate arrangement, 68% nitric corrosive and 32% water by mass, with a breaking point of 393.5 K.
