A solution in which no more solute can be dissolved at any fixed temperature is called a saturated solution. In a saturated solution, dissolved and undissolved solutes are in equilibrium with each other. Any more solute added will settle down at the bottom of the container as a precipitate.

E.g. If 500 g of a solvent can dissolve a maximum of 150 g of a particular solute at 300 K. Then, the solution obtained by dissolving 150 g of that solute in 500 g of that solvent at 300 K is said to be a saturated solution at 300 K.
