प्रश्न
Draw a table to differentiate – True solutions, colloidal solutions & suspensions – with respect to
- Type of mixture
- Solute particles in the mixture.

उत्तर
True solution:
- Homogeneous mixture.
- Particles are extremely small less than 1 nm in diameter = 10-9 m.
Colloidal:
- Appears to be homogeneous actually it is heterogeneous
- Between 1 nm and 100 nm in diameter.
Suspension:
- Heterogeneous mixture.
- Size larger than 100 nm in diameter. Quite large size.
