In a solution, what is the term for the substance that exists in the smaller amount?

In any solution, the substance that exists in the smaller amount is referred to as the solute. The solute is the component that is dissolved in the solvent, which is the substance present in the larger amount. For example, when salt is dissolved in water, salt is the solute, while water is the solvent. The interaction between the solute and the solvent produces a homogeneous mixture known as a solution.

Understanding this distinction is fundamental in various scientific fields, including chemistry and biology, as it helps clarify the roles of different components within mixtures. The correct terminology is essential for effectively communicating concepts related to solutions and their properties.
