Description
Lecture 3 (1/10/2013) • Colligative Properties of Solutions o Colligative Properties:  Solution properties that depend on concentration of solute  particles, not the identity of particles.  • Solute Concentration: Molality o Changes in boiling point/freezing point of solutions depends on molality: moles of solute m = o                     kg of solvent o Preferred concentration unit for properties involving temperature changes  because it is independent of temperature. o For typical solutions: molality > molarity. • Boiling­Point Elevation and Freezing­Point Depression o Boiling Point Elevation (ΔT ): b  ΔT b= K ∙b  K b= boiling point elevation constant of solvent; m = molality. o Freezing Point Depression (ΔT): f  ΔT f K∙mf  K f freezing­point depression constant; m = molality. • The van’t Hoff Factor o Solutio
