Question
How are sol, solution and suspension different from each other?
Answer
| Property | Solution | Sol (Colloid) | Suspension |
| Type of Mixture | Homogeneous mixture. | Heterogeneous mixture (appears homogeneous). | Heterogeneous mixture. |
| Particle Size | Very small (< 1 nm). | Intermediate (1 nm - 100 nm). | Large (> 100 nm). |
| Visibility | Particles are not visible to naked eye. | Particles are not visible to naked eye. | Particles are often visible to naked eye. |
| Light Scattering | Does not scatter light. | Scatters beam of light (Tyndall effect). | Scatters beam of light. |
| Stability | Stable (particles do not settle). | Stable (particles do not settle). | Unstable (particles settle down). |
| Filtration | Cannot be separated by filtration. | Cannot be separated by filtration. | Can be separated by filtration. |
| Examples | Salt solution, sugar solution. | Milk, blood, starch solution. | Muddy water, sand in water. |
