Colligative properties depend on ___________.
Show Hint
Colligative properties are properties of the solutions that depend on the concentration of the solute ions or molecules.
- the nature of the solute particles dissolved in solution
- the number of solute particles in solution
- the physical properties of the solute particles dissolved in solution
- the nature of solvent particles
The Correct Option is B
Solution and Explanation
Colligative properties are properties of the solutions that depend on the concentration of the solute ions or molecules. They do not depend on the identity of the solute. It is used to determine the molecular mass of the particle.
The four colligative properties are:
- Relative Lowering of the vapor pressure of the solvent
- Osmotic pressure
- Elevation in the boiling point of the solvent.
- Depression at the freezing point of the solvent.
These colligative properties depend on the number of particles and not on the nature of particles dissolved.

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.
