Explain the term 'colligative property'. Why do we sometimes get abnormal molecular masses of the substances using colligative properties of the solution?

Explanation

### Step-by-Step Text Solution

**Step 1: Define Colligative Property**
Colligative properties are properties of solutions that depend on the number of solute particles in a given amount of solvent, rather than the identity of the solute. The main colligative properties include:
- Elevation of boiling point
- Depression of freezing point
- Osmotic pressure
- Vapor pressure lowering
