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.
