Question:
The solution having lowest freezing point is
The solution having lowest freezing point is
Updated On: May 12, 2024
- 0.1 M potassium chloride
- 0.1 M potassium sulphate
- 0.1 M potassium nitrate
- 0.1 M aluminium sulphate
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Depression in freezing point is a colligative property. Higher the value of i, higher will be depression in freezing point and lowest will be the freezing point of solution.
For � $ {KCl, }$ � � � � � � $ i = 2$
� � � $ {KNO_3, }$ � � � $ � � � i = 2$
� � � $ {K2SO4 }$ � � � � $ i = 3$
� � � $ {Al_2(SO_4)_3}$ � � � $ i = 5$

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.
