1 1 Properties of Solutions Today’s Lecture 17.4 The Vapor Pressures of Solutions 17.5 Boiling Point Elevation and Freezing Point Depression 17.6 Osmotic Pressure 17.7 Colligative Properties of Electrolyte Solutions 1 e.g. consider a scenario where two volatile liquids are present in solution (i.e. liquid-liquid solution) need a modified form of Raoult’s law for two volatile Cases Involving Volatile Components need a modified form of Raoult s law for two volatile components: where P Total represents the total vapor pressure of a solution containing A and B P Total = P A + P B = χ A P o A + χ B P o B 2 χ A and χ B are the mole fractions of A and B P o A and P o B are the vapor pressures of pure A and pure B P A and P B are the partial pressures resulting from molecules of A and B in the vapor state above the solution
