What happens when you add more solute to a saturated solution?
The solute normally doesn't dissolve and sinks to the bottom of the container.
However, some saturated solutions can become super-saturated for a given temperature and pressure, by altering the conditions without allowing solute to precipitate.
A solution that does not allow any more solute to dissolve (at room temperature) is called a SATURATED SOLUTION. But a saturated solution can be made to dissolve more solute by heating it. Then it is called a super saturated solution. The solvent becomes saturated and the no more solute will disolve
A saturated solution contains the maximum amount of solute (what is being dissolved) dissolved in an amount of solvent (what you are sticking the solute in). If you add more solute to a saturated solution, it will not dissolve. An unsaturated solution is opposite of this. It can dissolve more solute.
