|
boiling point elevation |
the temperature difference between a solutions boiling point and a pure solvents boiling point. |
|
|
colligative property |
depends on the ratio of the number of solute particles to solvent particles. 2 ways to express: Molality and Mole fraction |
|
|
concentrated solution |
contains a large amount of solute |
|
|
concentration |
the amount of solute dissolved in a given quantity of solvent. |
|
|
dilute solution |
a small amount of solute |
|
|
freezing-point depression |
the difference in temperature between the freezing point of solution and the pure solvent. |
|
|
Henry's law |
states that at a given temperature the solubility of a gas in a liquid (S) is directly proportional to the pressure of the gas above the liquid (P). S1 S2 ___ = ___ P1 P2 |
|
|
immiscible |
liquids that are insoluble in one another |
|
|
miscible |
2 liquids dissolve in one another |
|
|
molal boiling-point elevation constant (Kb) |
equal to the change in boiling point for a 1 molal solution of a non-volatile molecular solute. |
|
|
molal freezing-point depression constant (Kf) |
equal to the change in the freezing point for a 1 molal solution of a non-volatile molecular solution. |
|
|
molality (m) |
the number of moles of solute dissolved in 1 kg of solvent. |
|
|
molarity (M) |
the number of moles of a solute dissolved in 1 liter of solution (way to express concentration) |
|
|
mole fraction |
the ratio of moles of solute in solution to the total number of moles of both solvent and solute. |
|
|
saturated solution |
contains the maximum amount of solute for a given amount of solvent at a constant temperature. |
|
|
solubility |
the amount of a substance that dissolves in a given quantity of a solvent at a given temperature to produce a saturated solution. |
|
|
supersaturated solution |
contains more solute than it can theoretically hold at a given temperature. |
|
|
unsaturated solution |
a solution that contains less solute than a saturated solution. |
