As solute is dissolved in a solvent, the vapor pressure of the solution changes according to Raoult's law Psoln=Psolv×Xsolv where Psoln is the vapor pressure of the solution, Psolv is the vapor pressure of the pure solvent, and Xsolv is the mole fraction of the solvent. If the solute dissociates into ions, the term Xsolv must be modified to take into consideration the total number of moles of particles in the solution, both ions and molecules. When a solution contains...
