How are the following colloids different with respect to dispersed phase and dispersion medium ? Give one example of each
(i) Aerosol (ii) Emulsion (iii) Hydrosol.

Explanation

To differentiate the colloids based on their dispersed phase and dispersion medium, let's analyze each type: aerosol, emulsion, and hydrosol.

### Step-by-Step Solution:

1. **Aerosol**:
- **Dispersed Phase**: The dispersed phase in an aerosol can be either liquid or solid particles.
- **Dispersion Medium**: The dispersion medium is a gas.
- **Example**: Smoke (solid particles dispersed in air) or fog (tiny water droplets dispersed in air).
