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
