What term describes the dissolved substance in a solution?

The term that describes the dissolved substance in a solution is "solute." In a solution, the solute is the component that is present in a lesser amount and is what gets dissolved, while the solvent is the larger component that does the dissolving. Together, the solute and solvent create a homogeneous mixture known as a solution. For example, in a saltwater solution, the salt is the solute that dissolves in water, the solvent. Concentration gradient refers to the difference in the concentration of a substance across a space and is not a term that describes a component of a solution.
