How are sol, solution and suspension different from each other?
Solution – Completely mixed, clear (like salt water).
Sol (Colloid)– Looks smooth but has tiny particles (like milk).
Suspension – Particles are big and settle down (like muddy water).
| Property | Solution | Sol (Colloidal solution) | Suspension |
|---|---|---|---|
| Type of mixture | Homogeneous | Heterogeneous (appears uniform) | Heterogeneous |
| Particle size | Very small (can’t be seen) | Medium size (not visible clearly) | Large (can be seen with eyes) |
| Settling of particles | Do not settle | Do not settle | Settle down over time |
| Visibility | Clear and transparent | Appears cloudy or opaque | Particles are clearly visible |
| Tyndall effect | No | Yes (scatters light) | Yes (if particles are large enough) |
| Examples | Salt in water, sugar in water | Milk, blood, starch in water | Mud in water, sand in water |
