Interpretation:The colligative property has to be defined.
Concept Introduction: Colligative properties depend on the number of solute particles in the solution.
“i” is the number of particles that the solute will dissociate upon mixing with the solvent. With the help of molality of a solution and the number of particles a compound will dissolve to form, it is possible to predict the solution with lowest freezing point.

Answer to Problem 49A
The properties of a solution, which depend on the number, not the identity of the solute particles is known as the colligative properties.
Explanation of Solution
The properties of a solution, which depend on the number, not the identity of the solute particles is known as the colligative properties.
Colligative properties depend on the number of solute particles in the solution.
“i” is the number of particles which the solute will dissociate upon mixing with the solvent. With the help of molality of a solution and the number of particles a compound will dissolve to form, it is possible to predict the solution with lowest freezing point.
The colligative properties includes,
- Vapor pressure depression of the solvent
- Elevation of the boiling point
- Depression in the freezing point
- Osmotic pressure
The properties of a solution, which depend on the number, not the identity of the solute particles is known as the colligative properties.
