The definition of a saturated solution.

• A saturated solution is one that contains the maximum concentration of solute that can be dissolved at a specific temperature and pressure.

• A saturated solution is one that has a lower concentration of solute than a supersaturated solution.

• A saturated solution is one that can dissolve any amount of solute regardless of temperature.

• A saturated solution is one that contains no solute at all.

The definition of a supersaturated solution.

• A supersaturated solution is a solution that contains more dissolved solute than what is typically possible at a given temperature.

• A supersaturated solution is a solution that contains only the maximum amount of solute possible.

• A supersaturated solution is a solution that has no dissolved solute at all.

• A supersaturated solution is a solution that is in equilibrium with undissolved solute.

What is the solubility product constant (Ksp) used to describe?

• The rate at which a solute dissolves in a solvent

• The equilibrium between a solid and its ions in a saturated solution

• The concentration of solute in a saturated solution

• The temperature at which a solute dissolves
