How do suspensions differ from solutions?
Suspensions are heterogeneous, solutions are homogeneous.
Suspensions consist of more than one homogenous phase, for example, a suspension of clay particles in water consists of small solid particles suspended in liquid. A suspension of oil in water consists of two non-miscible liquid phases with a distinct interface between the two liquid phases.
Solutions, on the other hand, consist of just one homogeneous phase - sodium chloride in water, sodium and chloride ions are solvated completely by water - there is no bulk solid dispersed or suspended in the water.
