A saturated solution can dissolve more when you increase its temperature and less when you decrease. When hot saturated solution is cooled to zero degrees Celsius, or beyond it the solubility of the solvent will decrease and precipitate until it forms a solid.
A saturated solution is one that has reached its saturation level for a specific solute (what is dissolved in it). The saturation level depends on the temperature and different solutes have different saturation levels at different temperatures.
When a saturated solution is cooled, one of two things can happen.
A supersaturated solution is obtained.
Supersaturated
A supersaturated solution is obtained.
The solute can re-form as a solid.
This is a saturated solution.
The solute will eventually fall out of a supersaturated solution
A supersaturated solution is obtained.
Salt will crystalize out.
The solute will eventually fall out of a supersaturated solution
Adding more solute the solution become supersaturated.
Supersaturated
A supersaturated solution is obtained.
A solution become supersaturated when the limitt of solute solubility at a given temperature is exceeded.
The solute can re-form as a solid.
A supersaturated solution has a concentration of solute greater than the solubility at a specific temperature.
How a saturated solution can become supersaturated?
A supersaturated solution contain an amount of solute higher than the limit of solubility at a given temperature and pressure.
