Solution
| Property | Sol | Solution | Suspension | |
| 1. | Nature | Heterogeneous | Homogeneous | Heterogeneous |
| 2. | Particle size (diameter) | Between 10-7 to 10-5 cm (10-9 to 10-7 m or 1 nm to 100 nm) | Less than 1 nm (less than 10-9 to 10-7 m) | More than 100 nm |
| 3. | Appearance | Generally clear | Clear | Opaque |
| 4. | Visibility | Visible with ultramicroscope | Not visible | Visible with naked eyes |
| 5. | Diffusion | Diffuses very slowly | Diffuses rapidly | Does not diffuse |
| 6. | Tyndall effect | Shows | Does not show | Shows |
| 7. | Settling of particles | Settle only on centrifugation | Does not settle | Settle of their own |
