Recall that solubility is the maximum amount of solute that can be dissolved in a certain amount of solvent at a specific temperature. This is different from Rate of Solubility. Three factors that affect the rate of solubility are (1) temperature, (2) agitation (e.g. stirring), and (3) surface area (e.g. grain size, which is inversely related to surface area). Note: The word "rate" always includes a measurement of time; less time means faster process, and more time means slower process.

12-14. Solubility depends on the rule "like dissolves like," such as (a) polar substances dissolving ionic/polar substances or (b) nonpolar substances dissolving nonpolar substances.
