When a solute's concentration equals its solubility, the solution is said to be:
AColloidal
BImmiscible
CSaturated
DVery dilute
Answer & Solution
Correct answer: C. Saturated
1. Solubility marks a ceiling on concentration.
2. The concentration of sugar in solution at the limiting point is known as its solubility.
3. When a solute's concentration is equal to its solubility, the solution is saturated.
4. Beyond that point the solution would hold more than solubility allows.
