What is a saturated solution?

1. A solution that contains no solute

2. A solution that has the maximum amount of dissolved solute

3. A solution that has a high concentration of solvent

4. A solution that is only temporarily stable

The correct answer is: A solution that has the maximum amount of dissolved solute

A saturated solution is defined as a solution that has the maximum amount of dissolved solute at a given temperature and pressure. This means that no more solute can be dissolved in the solvent under those conditions; the solution is in equilibrium with the solid solute. When you add more solute to a saturated solution, it will not dissolve and will remain as undissolved solid at the bottom of the container. Thus, the characteristic of being a saturated solution is intrinsically linked to reaching its solubility limit. The other options describe characteristics that do not align with the concept of saturation. A solution with no solute does not meet the definition of saturation, as saturation specifically involves having solute present. A high concentration of solvent does not pertain to saturation, since saturation is focused on the solute's concentration. Lastly, a solution only temporarily stable does not accurately describe a saturated solution, which is stable as long as conditions remain constant and undisturbed.
