Factors affecting rate of dissolution:
Stirring (agitation), temperature, surface area
Stirring will introduce new solvent to the solute, therefore increasing rate of dissolution.
A higher temperature will increase collisions and allow particles to dissolute in the solvent quicker.
A lower surface area will allow for more solvent to go around the particles, thus creating a quicker rate of dissolution.

Colligative Properties:
Freezing Point Depression-the difference in temperature between the freezing point of a solution and the freezing point of the pure solvent
Boiling Point Elevation-the difference in temperature between the boiling point of a solution and the boiling point of the pure solvent
Vapor Pressure Lowering-the decrease in a solution's vapor pressure is proportional to the number of particles the solute makes in solution
