the solution contains more solute than a saturated solution (both under the same temperature)
3
Q
How does temperature affect solid, liquds and gases?
A
- solids: when temperature increases -> solubility increases
- Liquids: unaffected
- Gases: solubility decreases when temperature increases
4
Q
How does pressure affect solubility?
A
- affects gases significantly
- solids and liquids are unaffected
