Nonvolatile nonelectrolyte solutions

The molal boiling point elevation constant, S), is the difference in boiling points between aim nonvolatile, nonelectrolyte solution and a pure solvent. It is expressed in units of °C/w and varies for different solvents. Values of A j, for several common solvents are found in Table 15-4. Note that water s A j, value is 0.512°C/w. This means that a m aqueous solution containing a nonvolatile, nonelectrolyte solute boils at 100.512°C, a temperature 0.512°C higher than pure water s boiling point of 100.0°C. 

Values of for several common solvents are found in Table 15-5. As with K values, values are specific to their solvents. With water s value of 1.86°C/m, a Im aqueous solution containing a nonvolatile, nonelectrolyte solute freezes at -1.86°C rather than at pure water s freezing point of 0.0°C.

Recall from Section 11.5 that the vapor pressure of a hquid is the pressure of the gas above the liquid when the two are in dynamic equihbrium (that is, when the rate of vaporization equals the rate of condensation). What is the effect of a nonvolatile nonelectrolyte solute on the vapor pressure of the liquid into which it dissolves The basic answer to this question is that the vapor pressure of the solution is lower than the vapor pressure of the pure solvent. We can understand why this happens in two different ways.
