How is a saturated solution defined?

A saturated solution is defined as one that contains the maximum amount of solute that can be dissolved in a given amount of solvent at a specific temperature and pressure. This means that the solution is in equilibrium; no additional solute can dissolve in the solvent without changing the conditions (like temperature or pressure).

When a solution reaches saturation, any added solute will remain undissolved, indicating that the solute concentration has officially hit its limit. This fundamental concept is crucial in understanding solubility and concentration, as well as reactions in solution where saturation plays a key role.
