Solubility Curves

• show how much solute will dissolve in water at a
  given temperature
• Table G shows a solubility curve

3
Solubility Curves for Gases
As temperature goes up, gases become less
soluble in water
4
Solubility Curves for solids
As temperature goes up, solids become more
soluble in water
