What is Sol, solution and suspension different from each other?

Dear student ,
The differences between sol, solution and suspension are:
Sol (Colloidal solution) Solution Suspension
They are heterogeneous in nature They are homogeneous in nature They are heterogeneous in nature
 The particles of a colloid are too small to be individually seen by naked eyes.  The particles of a true solution cannot be distinguished from the solvent particles. The particles of a suspension can be seen by the naked eye.
The size of colloidal particles lies between 1nm to 1000nm. The size of solute particles is less than 1nm. The size of suspended particles is more than 1000nm.
 They scatter a beam of light and hence show Tyndall effect.  They do not scatter a beam of light and hence do not show Tyndall effect.  They do not scatter a beam of light and hence do not show Tyndall effect.
 They do not settle down when left undisturbed. They are quite stable  Particles of solution do not settle down at the bottom when left undisturbed. They are very stable  The solute particles settle down when a suspension is left undisturbed. They are unstable
 Examples of sol are: milk, blood smoke etc.  Examples of solution are: salt in water, sugar in water.  Examples of suspension are: sand in water, dusty air
