Understanding Solutions and Their Properties

What is an unsaturated solution?

• A solution that contains more solute than it can theoretically hold at a given temperature.

• A solution that contains less solute than it can theoretically hold at a given temperature.

• A solution that contains exactly the maximum amount of solute it can hold at a given temperature.

• A solution that cannot dissolve any more solute at any temperature.

Which of the following best describes a saturated solution?
