Suspensions

Suspensions refer to a heterogeneous mixture in which solid particles are dispersed throughout a liquid or gas but are not dissolved. These particles are typically larger than those found in solutions and can be seen with the naked eye or through a microscope. Over time, the solid particles in a suspension will settle out of the mixture if left undisturbed, due to the force of gravity, which distinguishes suspensions from solutions where solute particles remain uniformly distributed. Common examples of suspensions include muddy water, paint, and certain medications that require shaking to ensure an even distribution of the active ingredients. In scientific contexts, suspensions can also refer to the temporary cessation of an activity or process, such as a suspension of a license or privilege.
