Which of the following aqueous solution has highest freezing point ?
Updated On: Apr 2, 2024
- $0.1 $ molal $Al_2(SO_4)_3$
- $0.1 $ molal $BaCl_2$
- $0.1 $ molal $ Al_2Cl_3$
- $0.1 $ molal $NH_4Cl$

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Colligative property $\alpha$ number of particles after dissociation or association means less be the number of particles, more lower be the freezing point and more be the number of particle more lower be the freezing p?int.
Hence for $NH _{4} Cl , n=i=2$
which is gives least number of particle hence show highest freezing point.
Hence for $NH _{4} Cl , n=i=2$
which is gives least number of particle hence show highest freezing point.

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.
