Chemistry - Liquid Solution Question with Solution | TestHub

Colligative properties are those properties of dilute solutions which depend only on the number of solute particles and not on their nature.

The four important colligative properties are:
1. Relative lowering of vapour pressure
2. Elevation of boiling point
3. Depression of freezing point
4. Osmotic pressure

Vapour pressure, boiling point, and freezing point are not colligative properties by themselves; rather, their changes (relative lowering, elevation, and depression respectively) are colligative properties. Osmotic pressure is directly a colligative property.

Answer: Osmotic pressure
