Solubility

Solubility
-every combination of solute and solvent has a limit to the amount of solute that can be dissolved
-depends on nature of solute, solvent, and temperature
-solute molecules leave the solid surface and move around randomly
-when max solubility is reached, the amount of solid dissoluting is the same as the amount crystallizing
-solubility equilibrium- dissolution and crystallization of a solute occur at the same rate
Saturated vs. Unsaturated
-saturated-contains the maximum amount of dissolved solute
-unsaturated-contains any amount less than the maximum amount of dissolved solute
-supersaturated-upon cooling, the solute does not settle out of the solution, creating a solution with more than the maximum amount of solute dissolved at certain conditions
-"Like Dissolves Like"
-dissolution happens between two like substances
-type of bondin
-polarity of molecules
-intermolecular forces
-solutions with water involved as the solvent are hydrated
-liquids that do not dissolve in each other are immiscible
-liquids that dissolve freely in each other are miscible
