Question

What is suspension and colloid?

Answer 1

Suspensions and colloids are heterogeneous mixtures. A suspension is identifiable because its particles are large and settle out of the dispersing medium due to the effects of gravity. The dispersed particles of a colloid are intermediate in size between those of a solution and a suspension.

Answer 2

Suspensions is a heterogeneous mixture in which the solute particles do not dissolve but remain suspended throughout the bulk of the solvent.
a colloidal solution is a solution in which the size of solute particles is intermediate between those in true solution and suspension
