What term is used for a liquid containing dispersed, finely divided particles?

The correct term for a liquid containing dispersed, finely divided particles is "suspension." In a suspension, solid particles are distributed throughout a liquid but are not dissolved; they remain distinct and can settle over time if left undisturbed. The particles in a suspension are typically larger than those found in a solution, which involves particles that are completely dissolved.

Emulsions involve the combination of two immiscible liquids, where one liquid is dispersed in another, while dispersions can refer to a variety of mixtures, including suspensions, but do not specifically convey the notion of solid particles suspended in a liquid. Therefore, in the context of the precise definition needed for a liquid with finely divided particles, "suspension" aptly describes the scenario.
