Question

what are azeotropic mixture? give types and examples.​

Answer 1

Answer:

Azeotrope Mixture Types

Consider, for example, a negative azeotropic hydrochloric acid consisting of a weight concentration of approximately twenty per cent and 79 per cent of water. Examples: Separation of water and isobutanol. Dehydration of ethanol.

The most common example is the azeotrope between water and ethanol (grain alcohol). Water boils at 100 ºC and ethanol boils at 78.3 ºC. The mixture will boil at 78.2 ºC and have a composition of 95% ethanol and 5% water by volume. This is a binary azeotrope because it involves two components.

AZEOTROPIC MIXTURE

• An azeotrope is a liquid mixture that has a constant boiling point and whose vapor has the same composition as the liquid.

TYPES

• Minimum Boiling Azeotropes or Negative Azeotrope. Azeotropic mixtures with less boiling point are called negative azeotropes in their constitutions.
• Maximum Boiling Azeotropes or Positive Azeotrope.
• Heterogeneous and Homogeneous Azeotropes.
• Azeotropes Based on the Number of Constituents.

EXAMPLE

• The most common example is the azeotrope between water and ethanol (grain alcohol). Water boils at 100 ºC and ethanol boils at 78.3 ºC. The mixture will boil at 78.2 ºC and have a composition of 95% ethanol and 5% water by volume.
