Concept explainers
Interpretation:
The boiling point of an aqueous solution can be calculated with the help of freezing point temperature.
Concept introduction:
Molality is the number of moles of solute to the mass of solvent.
The mass of the solvent should be in kilograms
Calculate molality as follows:
The temperature at which change of liquid state to solid state takes is called freezing point.
The freezing point depression is as follows:
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 is known as boiling point.
The boiling point elevation is as follows:
Here,
molality of the solution in
constant for the solvent.
For water:
