Concept explainers
Interpretation:
The freezing point of an aqueous solution that boils at
Concept Introduction:
Molality is the ratio of number of moles to the mass of solvent.
The mass of the solvent should be in kilograms
Formula of molality is:
The temperature at which there is change of liquid state to solid state is called freezing point.
The freezing point depression is:
Here,
molality of the solution in
constant for the solvent.
For water:
The boiling point is the temperature at which vapor pressure of the liquid becomes equal to the atmospheric pressure.
The boiling point elevation is:
Here,
molality of the solution in
constant for the solvent.
For water:
