A saturated solution is a solution that contains the maximum amount of dissolved material possible. Any additional material added to the solution will not be dissolved into the solution.
Solutions are mixtures of homogenous components called solvents and solutes. Solutes are the materials dissolved into the larger solvent base, and they may take form as gases, liquids and solids.
Solutes can only be dissolved in certain amounts before they form into a separate phase and are unable to further dissolve. Saturated solution is also known as the maximum concentration of solutes and may be used in the process of recrystallization to create pure chemical concentrations.
