Explain why particles of a colloidal solution do not settle down when left undisturbed, while in the case of a suspension they do.

AcademicChemistryNCERTClass 9

The size of colloidal particles in a colloidal solution is smaller than in suspension. These particles are in a random motion, hence, they do not settle down when left undisturbed. The particles of suspension are bigger and they tend to settle down under the effect of gravity.
