What is the term for any mixture of two or more immiscible liquids where one liquid is dispersed in another?

The term for a mixture of two or more immiscible liquids, where one liquid is dispersed in the other, is called an emulsion. In this context, "immiscible" refers to liquids that do not mix well together, such as oil and water. An emulsion occurs when tiny droplets of one liquid are suspended within another, achieving a stable blend thanks to the addition of an emulsifying agent, which helps keep the two phases from separating.

In contrast, a suspension involves solid particles dispersed in a liquid, while a solution indicates a homogeneous mixture where one substance (the solute) is completely dissolved in another (the solvent). A mixture is a broader term that can apply to any combination of substances, regardless of their states or interactions. Thus, emulsion is the precise term used to describe the specific situation where two immiscible liquids coexist with one acting in a dispersed form within the other.
