Which of the following refers to a liquid that does the dissolving in a solution?

A liquid that does the dissolving in a solution is known as a solvent. In a solution, the solvent serves as the medium in which the solute is dissolved. The solvent typically makes up the majority of the solution and is essential for the creation of homogeneous mixtures, where the solute is evenly dispersed throughout the solvent.

In contrast, a solute is the substance that is dissolved in the solvent, resulting in the formation of a solution. Suspensions refer to mixtures in which solid particles are suspended in a liquid or gas, but they do not dissolve completely like solutes do in solvents. An elixir is a specific formulation that often contains a solvent along with active ingredients, usually with a sweetening agent, but it is not simply defined as the liquid that does the dissolving. Thus, the correct answer accurately identifies the role of a solvent in the context of solutions.
