A two-phase system of finely divided insoluble particles dispersed in a liquid is known as a(n):

An emulsion consists of two immiscible liquids mixed together, where one liquid contains a dispersion of the other in the form of tiny droplets. Common examples include oil in water or water in oil. Unlike suspensions, emulsions do not involve solid particles and are stabilized by emulsifying agents to prevent separation.

A tincture is a solution made by dissolving a substance—typically a medicinal herb—in alcohol or another solvent. Tinctures do not feature suspended particles; instead, they represent a homogeneous mixture where the solute is completely dissolved in the solvent, thus lacking the two-phase characteristic of a suspension.

A solution is a homogeneous mixture where a solute is completely dissolved in a solvent, resulting in no visible particles. In contrast to suspensions, solutions do not exhibit phase separation, as the solute particles are at the molecular or ionic level, rendering them invisible to the naked eye.
