8. Dissociation - Dissolving of Ionic Compounds
The dissolving of ionic compounds in which the ions separate from each other and the crystal lattice.
The resulting ions are called hydrated or aqueous ions.

9. Factors Affecting the Rate of Dissolving
What can make a solute dissolve faster?
Factor
Effect
Explanation
Particle Size
Temperature
Stirring
Smaller particles will dissolve faster
Increased surface area is exposed to solvent
Solute dissolves faster at higher temperatures
More frequent collisions between molecules
Agitating a solution increases the rate of dissolving
Fresh solvent continually comes into contact with the undissolved solute

10. Definitions
Saturated:
Unsaturated:
Supersaturated:

11. Testing for Saturation
Simply place a small crystal in a solution:
If the crystal gets smaller, the solution is unsaturated
If the crystal does not change, the solution is saturated
If the crystal grows, the solution is supersaturated
