Sample Questions on Azeotropic Mixture
Here are some sample question on Azeotropic mixtures that include,
Q1: What are Azeotropic Mixtures?
Azeotropic mixture is a mixture of two or more liquids with a similar boiling point and a similar composition in their vapor phase. Azeotropic mixture either has a higher or lower boiling point than its components.
Examples of Azeotropic Mixture:
- Water-Ethanol (95.6% ethanol, 4.4% water)
- Acetone-Chloroform (29.3% acetone, 70.7% chloroform)
- Sulfuric Acid-Water (98.3% sulfuric acid, 1.7% water)
- Hydrochloric Acid-Water (20.2% hydrochloric acid, 79.8% water)
Q2: What are Type of Azeotropic Mixture?
There are following main types of Azeotropic Mixture:
- Positive Azeotropes
- Negative Azeotropes
- Homogeneous and Heterogeneous Azeotropes
Q3: Explain Concept of Constant Boiling Azeotropes.
Because their composition is unchanged by distillation, azeotropes are also called constant boiling point mixtures.
Q4: Why is Distillation Challenging for Azeotropic Mixtures?
In the case of azeotropic mixtures, distillation becomes challenging due to the unique behavior of these mixtures, specifically their constant boiling points and vapor compositions at the azeotropic point. Here are the primary reasons why distillation is challenging for azeotropic mixtures:
- Constant Boiling Point
- Failure of Raoult’s Law
- Vapor-Liquid Composition Equality

Azeotropic Mixture
Azeotropic Mixture is a mixture of two or more liquids with a similar boiling point and a similar composition in their vapor phase. Unlike most mixtures, an azeotropic mixture has a constant boiling point and composition during the vaporization process. In this article, we will study the different concepts related to Azeotropic mixture in detail.
