Saturated or Unsaturated



Saturated or Unsaturated?

Concentration: the amount of solute dissolved in a given quantity of solvent.

- Dilute Solutions: solutions with a low amount of solute.

- Concentrated Solutions: solutions with a high amount of solute.

[pic]

Both dilute and concentrated solutions still contain unfilled spaces between the solvent particles so are called unsaturated solutions. A solution in which all the available spaces between the solvent particles are filled is called a saturated solution.

A solution that contains more of the solute than would be found in a saturated solution is called supersaturated. These solutions can be made by starting with a hot saturated solution at high temperature, and then allowing the solution to cool slowly. If the solution is not disturbed, all the solute may remain dissolved.

If a solute dissolves in a particular solvent, we say that it is soluble in that solvent. If a solute does not dissolve, it is insoluble in that solvent.

The solubility of a solute is the exact amount of solute required to form a saturated solution in a particular solvent at a certain temperature. The solubility is different for each combination of solute and solvent.
