Liquid Solutions:
Miscible – liquids that dissolve in each other: water & food colouring, water & alcohol
Immiscible – Liquids that don’t dissolve together (when you look at them, you can see
layers): Oil & Water
Types of Solutions:
Unsaturated - all solute dissolved
o
o
excess solvent
rate of dissolving > rate of solid reforming
Saturated - not all of the solute is dissolved
o
o
o
Rate of dissolving of solute is balanced by rate of it coming out of solution
Excess solute
Equilibrium established
 If you DISTURB the equilibrium (ex. Heat solution), you can increase solubility of solute
Supersaturated – more solute dissolved than normal
-Unstable
- Few examples
- Solute dissolved in solvent
- Rate of solid formation > rate of dissolving when a “seed” crystal is added
