Study Notes

A concentrated solution has a relatively large amount of dissolved solute.
A dilute solution has a relatively small amount of dissolved solute.
A concentrated solution can be obtained from a diluted one by increasing the amount of solute or decreasing the amount of solvent by heating.
A dilute solution can be obtained from a concentrated one by increasing the amount of solvent.

Solubility is the maximum quantity of solute in a definite amount of solvent at specific conditions.
An unsaturated solution has a quantity of solute less than its solubility dissolved in a definite amount of solvent at specific conditions.
A saturated solution contains the maximum amount of solute (equal to its solubility) dissolved in a definite amount of solvent at specific conditions.
A supersaturated solution contains more than the maximum amount of solute that is capable of being dissolved at a given temperature.

Factors that affect the rate of dissolving a solid solute in a liquid solvent are temperature, stirring (shaking), and increasing the surface area of the solute.
Increasing temperature, stirring (shaking), and increasing the surface area of the solute increase the dissolving rate.
The solubility of a gaseous solute in a liquid solvent increases by decreasing the temperature and stirring (shaking).
