In a solution, what is the solvent?

• A. The substance that dissolves the solute.
• B. The substance that is identical to the solute.
• C. The substance formed when the solute reacts with the solvent.
• D. The substance in which the solute is dissolved, usually present in greater quantity.

Answer: (D)

In a solution, the key idea is that one component acts as the medium in which the other is dispersed, and this medium is the component present in the larger amount. That is why the solvent is defined as the substance in which the solute is dissolved, and it is usually present in greater quantity than the solute. This framing captures both the dissolution relationship and the quantity aspect that defines a solution’s structure. The other descriptions are incomplete or inaccurate for a general solution. Saying the solvent is just “the substance that dissolves the solute” describes a function but doesn’t emphasize which part is the bulk phase. A solution isn’t simply the same substance as the solute, and a new substance formed by a reaction between solvent and solute isn't the typical description of a simple solution.
