How are sol, solution and suspension different from each other?
Answer
|
Sol* |
Solution |
Suspension |
|
It is a heterogeneous mixture |
It is a homogeneous mixture |
It is a heterogeneous mixture |
|
Size of particles is neither too small nor too large (1 - 100nm) |
Size of particles are very small (less than 1nm) |
Size of particles are large (more than 100nm) |
|
Particles of a colloid are too small to be seen by the naked eye |
Individual Particles cannot be seen by the naked eyes |
Particles of suspension can be seen by the naked eye |
|
Particles are stable , they do not settle down when left undisturbed |
Particles are stable , they do not settle down when left undisturbed |
Particles are not stable , they settle down after some time |
|
Particles are large enough to scatter a beam of light |
Particles of solution do not scatter light |
Particles are large enough to scatter a beam of light |
|
Particles are small enough to pass through filter paper, hence particles cannot be separated by filtration |
Particles pass through filter paper, hence particles cannot be separated by filtration |
Particles are large, they do no pass through filter paper, hence particles can be separated by filtration |

Examples Milk of magnesia, mud |
Examples Solution of Salt and Water, Sugar and Water |
Examples Mixture of chalk and water, sand and water |
*Sol is a type of colloid in which solid particles are suspended in a liquid, ie, the solvent is liquid and the solute is solid.
