Concept explainers
Interpretation:
The boiling point and freezing point of solution of given molar concentration of naphthalene in benzene is to be calculated.
Concept introduction:
The temperature at which change of liquid state to solid state occurs is called freezing point.
The freezing point depression is as follows:
Here,
For benzene
The actual freezing point is the difference between freezing point of pure solvent and freezing point depression.
The temperature at which vapor pressure of a particular liquid has the same value as the atmospheric pressure is called its boiling point.
The boiling point elevation is as follows:
Here,
For benzene:
The actual boiling point of the solution is the sum of boiling point of pure solvent and the boiling point elevation
