What term describes a solid substance that settles at the bottom of a container?

The term "precipitate" specifically refers to a solid substance that forms and settles out of a liquid solution as a result of a chemical reaction or a change in conditions, such as temperature or pH. In a chemical context, when certain compounds react in a solution, the resulting product may become insoluble and thus precipitates from the liquid, collecting as a solid at the bottom of the container.

In comparison, a solution is a homogeneous mixture where one substance (the solute) is completely dissolved in another (the solvent), with no visible solid settling at the bottom. A suspension is a heterogeneous mixture where solid particles are dispersed throughout a liquid but can settle out over time, while an emulsion involves the mixing of two immiscible liquids (like oil and water) where one liquid contains a dispersion of the other in small droplets. Thus, the context of the question specifically aligns with the definition of a precipitate as a solid that forms and settles out of a liquid mixture.
