Which of the following is a suspension?
Muddy Water
A suspension is a mixture in which the solute particles are larger in size, easily visible and insoluble in the solvent. Hence, they float throughout the solvent or stay suspended. These insoluble components settle to the bottom when left undisturbed for some time. Muddy water is a suspension as soil particles do not dissolve in water and settle down at the bottom after some time.
Fog, mist, and milk are colloids.
