Solution

The correct options are
A Elevation of boiling point
B Depression of freezing point
C Relative lowering of vapour pressure
D Osmotic pressure
The properties of the solution which depend only on the number of solute particles but not on the nature of the solute are called colligative properties of the solution.
All the above-mentioned properties belong to colligative properties. They all depend on the number of solute particles.

State True or False.

Relative lowering of vapour pressure is a colligative property.

Q. Assertion :Relative lowering of vapour pressure is equal to the mole fraction of the solvent
Reason:

Relative lowering of vapour pressure is a colligative property

Q. Assertion :Lowering of vapour pressure is not dependent on the number of species present in the solution. Reason: Lowering of vapour pressure and relative lowering of vapour pressure are colligative properties.

Q. Assertion :Osmotic pressure of
