A saturated solution is a mixture in which no more solute can dissolve in a solvent at a given temperature and pressure. This occurs when the solvent has reached its maximum capacity to dissolve the solute, resulting in a balance between the dissolved particles and the undissolved solute. Common examples include salt in water or sugar in tea. In a saturated solution, any additional solute added will remain undissolved, settling at the bottom. The concentration of the solute in a saturated solution is specific to the type of solute and solvent used, as well as the temperature, making it an important concept in chemistry and related fields like pharmacology and environmental science.
