True solution => a homogeneous mixture of two or more solutes in which substance dissolved in solvent forms a solution whose particles cannot be filtered or seen with naked eyes Eg. Salt solution.
Suspension /Coarse dispersion => This is a heterogeneous mixture in which particle size of one or more solutes can be see with naked eyes and even filtered eg a solution of mad.
Colloidal => Heterogeneous mixture in which particles are intermediate of true solution and suspension and in which particles are not visible and can be filtered using a filter paper. The particles are however big enough to be blocked by animal membrane or parchment paper. Example is smoke particles.
The difference between the three is the size of particles, visibility and the ability to be filtered.
