Suspension=>
1. In suspension the solute particles do mot dissolve in the solution and remain suspended in it. They settle down when left undisturbed for some time i.e. suspension is unstable.
2. The size of particles is more than 100nm.
3. They do not show tyndall effect.
Example=> chalk powder in water
Colloidal =>
1. In colloids the solutes are not fully dissolved in the solvent but appears to be dissolved. The solute particles do not settle down when left undisturbed for some time i.e. colloidal solutions are stable.
2. The size of solute particles is between 1 ro 100nm
3. They show tyndall effect.
Example=> Starch solution
