In a solution, which term correctly identifies the dissolving medium?

• A. The solvent
• B. The catalyst
• C. The solution
• D. The solute

Answer: (A)

The dissolving medium is the solvent. In a solution, the solvent is the substance doing the dissolving and is typically present in greater quantity, setting the environment in which the solute disperses. The solute is the substance that is dissolved, while the entire mixture is called the solution. Catalysts are substances that speed up reactions and are not part of the dissolution concept. For example, when sugar dissolves in water, water acts as the solvent, sugar is the solute, and the resulting mixture is the solution.
