1. Solubility Curves

2. Saturated solutions
Solutions in which additional solute cannot dissolve and excess solute will precipitate.
Maximum amount of dissolved solute at a given temperature and pressure.
Unsaturated solutions
Solutions that are not yet saturated, i.e. the solvent can still dissolve a further amount of solute.
Supersaturated solutions:
Sometimes, under special circumstances, a solvent can dissolve more than its maximum amount
This can be achieved by heating a solution, saturating it at a higher temperature, then allowing it to cool
Unstable solutions, any disturbance will usually cause rapid precipitation of the excess solute

3. Solubility UNSATURATED SOLUTION more solute dissolves
no more solute dissolves
SUPERSATURATED SOLUTION
becomes unstable, crystals form
concentration

4. Mind Maps In partners, create ONE mind map using the following terms:
solubility solute saturated
solution unsaturated supersaturated
heterogeneous solvent aqueous solution
homogeneous precipitate temperature

5. A solubility curve is a plot of solubility versus temperature.
The line represents a saturated solution.
Points below the line represent unsaturated solutions.
Points above the line represent a supersaturated solution.
