PRESENTATION OUTLINE
SOLUBILITY
a substance is the amount of that substance required to form a saturated solution with a specific amount of I solvent at a specified temperature
Suspensions
If the particles in a solvent are so large that they settle out or a mixture is needed to be constantly stirred or agitated
COLLOIDS
Particles that are intermediate in size between those in solutions and suspensions form mixtures
MOLALITY
The concentration of a solution expressed in moles of solute per Kg of solvent
ELECTROLYTE
substance that dissolves in water to give a solution that conducts electric current
NON ELECTROLYTE
substance that dissolves in water to give a solution that does not conduct an electric current
Colligative properties
Properties that depend on the concentration of solute particles but not on their identity
VAPOR PRESSURE LOWERING: The boiling point and freezing point of a solution differ from those of the pure solvent.
BOILING POINT ELEVATION: the difference between the boiling points of the pure solvent and a nonelectrolyte solution of that solvent
FREEZING POINT DEPRESSION: the difference between the freezing points of the pure solvent and a solution of a non- electrolyte in that solvent
