Molality (m)
The number of moles of solute dissolved per kilogram of solvent
Solubility
The amount that dissolves in a given quantity of a solvent at a given temperature to produce a saturated solution
Boiling - point elevation
The difference in temperature between the boiling point of a solution and that of the pure solvent
Henry's law
States that at a given temperature the solubility (S) of a gas in a liquid is directly proportional to the pressure (P) of the gas above the liquid
Unsaturated
A solution that contains less solute than a saturated solution
Immiscible
Liquids that are insoluble (don't dissolve ) in each other
Dilute solution
A solution that contains a low concentration of solute
Mole fraction
The ratio of the moles of solute in solution to the total number of moles of solvent and solute
Colligative properties
Properties which depend only on the number particles dissolved in a given mass of solvent
Molarity (M)
The number of moles of a solute dissolved per liter ofsolution
Miscible
Two liquids that dissolve in each other
Molal boiling-point constant
Equal to the change in boiling point for a 1-molal solution of a nonvolatile molecular solute
Saturated solution
Contains the maximum amount of solute for a given amount of solvent at a constant temperature
Concentrated solution
A solution that contains a high concentration of solute
Solute
dissolved particles in a solution
Freezing-point depression
The difference in temperature between the freezing point of a solution and that of a pure solvent
Supersaturated solution
A solution that contains more solute than it should theoretically hold at a given temperature
Concentration
A measure of the amount of solute that is dissolved in a given quantity of solvent
Molal freezing-point constant
Equal to the change in the freezing point for a 1-molal solution of nonvolatile molecular solute
Solvent
The dissolving medium in a solution
