Learn what boiling point elevation is and how it depends on the concentration of solute in a solution. Find out how to calculate the boiling point of a solution using the formula and see solved examples.
The boiling point elevation happens both when the solute is an electrolyte, such as various salts, and a nonelectrolyte. In thermodynamic terms, the origin of the boiling point elevation is entropic and can be explained in terms of the vapor pressure or chemical potential of the solvent.
ΔTb = Tb(solution) − Tb(solvent) = Kb × m. where ΔTb is the boiling point elevation, Kb is the boiling point elevation constant, and m is the molality (mol/kg solvent) of the solute. A solution is prepared when 1.20 g of a compound is dissolved in 20.0 g of benzene. The boiling point of the solution is 80.94 o C.

Boiling point. Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [ 1][ 2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental ...
