1.6C: Understand How to Plot and Interpret Solubility Curves

SOLUBILITY: How much of a substance will dissolve in a given volume of a solvent (shown in the units of g per 100g of solvent)

s

• If a substance is soluble, it will dissolve in a given amount of solvent (liquid)
• Solubility increases as temperature and pressure increases

EXAMPLE OF INTERPRETING SOLUBILITY CURVES:

SOLID	EXPLANATION
A	As temperature increases, solubility of Solid A increases the most
B	As temperature increases, solubility of Solid B increases but at a slower rate than Solid A
C	Temperature does not affect the solubility of Solid C
