Solute Definition

A solute is defined as the substance that is dissolved in a solution. For solutions of fluids, the solvent is present in greater amount than the solute. Concentration is a measurement of the amount of solute present in a chemical solution, with respect to the amount of solvent.

Examples of Solutes

Usually, a solute is a solid that is dissolved into a liquid. An everyday example of a solute is salt in water.

Salt is the solute that dissolves in water as the solvent to form a saline solution.

On the other hand, water vapor is considered a solute in air, since nitrogen and oxygen are present in much larger concentration levels in the gas.

Solutes and solvents may also be applied to alloys and solid solutions. Carbon may be considered a solute in steel, for example.
