Colligative Properties include:
- - Boiling point elevation
- - Freezing point depression
- - vapor pressure decrease
- - osmotic pressure alteration
Chemical principles:
- - molality (m) = moles of solute/kg solvent [similar to molarity (M)]
- - cryoscopic constant (kf = ...for freezing, kb = ...for boiling) (see list here)
- - van't Hoff factor = an integer value indicating the number of solute particles resulting.
- - ΔT = kf/kb x m x i
Demonstration:
- - Seltzer water...
Experiment:
- - temperature of various salt water solutions.
