Question Question 4
Differentiate between:
(a) Solution and suspension
(b) Suspension and colloid
(a) Difference between Solution and suspension:
| Solution | Suspension |
|---|---|
| Solution is a homogeneous mixture. | Suspension is a heterogeneous mixture. |
| Particle size less than 10-10 m. | Particle size greater than 10-7 m. |
| It is transparent. | It is opaque. |
| Particles of solute are invisible. | Solute particles are visible. |
| Particles of solute do not settle. | Solute particles settle at the bottom of the container. |
| Solute particles cannot be filtered. The solution passes easily through a filter paper. | Solute particles do not pass through a filter paper. |
(b) Difference between Suspension and colloid:
| Suspension | Colloid |
|---|---|
| Particle size greater than 10-7 m. | Particle size between 10-10 - 10-7 m. |
| It is opaque. | It is translucent. |
| Solute particles are visible. | Solute particles can be seen with the help of a powerful microscope. |
| Solute particles settle at the bottom of the container. | Solute particles do not settle. |
| Solute particles do not pass through a filter paper. | Solute particles pass easily through ordinary filter papers but do not pass through ultra fine filters or nano filters. |
