1. saturated solution - a solution that contains the maximum amount of solute that it can dissolve.

2. supersaturated solution - a solution that contains solute whose amount is greater than the maximum amount that the solute that it can dissolve

3. unsaturated solution - the solute contained is less than the maximum that the solvent can dissolve.

Note: all these should have specific volume of solvent
