Types of Solutions

•Saturated

ØSolvent holds as much solute as is possible at that temperature.

ØDissolved solute is in dynamic equilibrium with solid solute particles.

•Unsaturated

ØLess than the maximum amount of solute for that temperature is dissolved in the solvent.

•Supersaturated

ØSolvent holds more solute than is normally possible at that temperature.

ØThese solutions are unstable; crystallization can usually be stimulated by adding a “seed crystal” or scratching the side of the flask.
