Vapor pressure lowering |
Lowering of vapor pressure is equal to the mole fraction of the solute |
Mole fraction |
|
|
Elevation of boiling point |
A direct consequence of the reduction of the vapor pressure by the added solute is that the temperature at which the vapor pressure of the solution attains atmospheric pressure (boiling point) must be higher than that of the pure solvent |
Consequence |
|
|
Depression of the freezing point |
Consequence of Lowering the vapor pressure is that the freezing point of the solution is lower than that of the pure solvent. The freezing point of the solution is the temperature at which the solution exists in equilibrium with solid solvent In such equilibrium, the solvent must have the same vapor pressure in both solid and liquid states. |
