Azeotropic mixture of water and HCl boils at 381.5 K. By distilling the mixture it is possible to obtain
- Pure HCl only
- Pure water only
- Neither water nor HCl
- Both water and HCl in pure state
The Correct Option is C
Solution and Explanation
The azeotropic mixture of water and HCl is a mixture in which the two components boil at a constant temperature, and their composition in the vapor phase is the same as in the liquid phase. In the case of water and HCl, this azeotrope forms at a temperature of 381.5 K.
When you distill an azeotropic mixture, it's typically not possible to separate the components into pure states using a simple distillation process. The reason for this is that the composition of the vapor and liquid phases remains constant at the azeotropic point. In the case of water and HCl, as you distill the mixture, the vapor you collect will have the same composition as the liquid you started with, which is the azeotropic composition.
Therefore, You cannot obtain either pure water or pure HCl by distilling the azeotropic mixture because the composition remains constant at 381.5 K.
So, the correct option is (C): Neither water nor HCl.

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
