Which term corresponds to 'Substance that dissolves in a solution'?

• A. Solvent
• B. Buffer
• C. Solute
• D. Density

Answer: (C)

In solutions, the component that is dissolved is the solute. The substance doing the dissolving is the solvent. For example, when table salt dissolves in water, salt is the solute and water is the solvent. This distinction helps explain many environmental scenarios, like contaminants (solutes) spreading in groundwater (the solvent). A buffer is a solution that resists pH changes because of a weak acid–base pair, not about what dissolves. Density is a physical property describing mass per volume, not about dissolution.
