Question: 1 / 495

A material that settles out of a reaction is called what?

Precipitate

A material that settles out of a reaction is referred to as a precipitate. This term is used specifically in the context of solutions, where a reaction occurs that causes a solute to become insoluble, resulting in the formation of a solid that separates from the liquid mixture. This can happen in various chemical reactions, including precipitation reactions, where two soluble reactants combine to form an insoluble product.

In contrast, the term product refers to the substances that result from a chemical reaction but does not specifically denote whether they are solid, liquid, or gas. A reactant signifies any starting material that undergoes a chemical transformation, and the term solid is a physical state of matter rather than a specific outcome of a reaction. Thus, the term precipitate is the most accurate and specific choice for describing a material that has settled out of a reaction.
