The term that describes a substance that can be dissolved in solution is solute.

Here's a breakdown:

* Solute: The substance that dissolves in a solvent to form a solution.

* Solvent: The substance that dissolves the solute.

* Solution: A homogeneous mixture formed when a solute dissolves in a solvent.

For example, in a sugar solution, sugar is the solute and water is the solvent.
