What is a solute?
AA solution component present at less than the solvent's concentration
BA solution component that has been added most recently
CA solution component that is solid before being dissolved
DA solution component that raises the boiling point
Answer & Solution
Correct answer: A. A solution component present at less than the solvent's concentration
1. A solution is made of a solvent plus one or more other components.
2. A solute is a component typically present at a much lower concentration than the solvent.
3. Nothing in that definition requires the solute to be a solid before dissolving.
4. Solute concentrations are described qualitatively as dilute or concentrated.
