Solution, Suspension and Colloid

del-pic

A Solution is a mixture that is homogenous and is made up of one or more solutes dissolved in a solvent. The solvent is present in mixture in the largest amount when compare to the solute(s).

A Suspension is a heterogeneous mixture containing particles that undergo sedimentation from the solvent-like phase. This occur sometime after the particle introduction to solvent-like phase.

A Colloid is a heterogeneous mixture made up of a solvent and suspended particles. The particles because of their small size will not undergo sedimentation.
