<strong>16</strong>.4 Freezing-Point Depression and Boiling-PointElevation• How are freezing-point depression and boiling-pointelevation related to molality?• The magnitudes of the freezing-point depression (ΔT f )and the boiling-point elevation (ΔT b ) of a solution aredirectly proportional to the molal concentration (m), whenthe solute is molecular, not ionic.<strong>16</strong>.4• The constant, K f , is the molal freezing-pointdepression constant, which is equal to the change infreezing point for a 1-molal solution of a nonvolatilemolecular solute.37
