Question

Ethanol and water form minimum boiling azeotropic mixture .Why ?​

Answer 1

The boiling point is low because the mixture has weak intermolecular forces and shows positive deviation.

Explanation:

• The mixture of water and ethanol is an azeotropic mixture and it has a low boiling point.
• A positive azeotrope mixture is formed when the boiling point is less than the actual boiling point.
• Such mixtures show positive deviation from Raoult's Law.
• As the boiling point of the mixture is low therefore the vapor pressure of the mixture would be high.

Answer 2

The Boiling point is low because the mixtures has weak intermolecular forces
