What are colligative properties?

What do you understand by a colligative property?

What is a colligative property? Give two examples.

Answer 1

The properties of solutions which depend upon the number of solute particles (molecules or ions) present in a definite amount of solvent, but not on the chemical nature of the solute, are called colligative properties.

The important colligative properties of solutions are as follows:

1. Relative lowering of vapour pressure
2. The elevation of boiling point
3. The depression of freezing point
4. Osmotic pressure
