Colligative Properties, Colloids, Surfactants

Colligative properties of solutions – properties depending on number of particles (ions, molecules) dissolved
Raoult’s Law of vapor pressure lowering: vp = vp_o(mol. frac. solvent)
Elevation of b.p. and depression of f.p. similar: DT = K(molality)
Use these to determine molar masses of solutes
V der W’s alpha: anomalous results due to ionic dissociation
Osmosis: flow of solvent across semipermeable membranes; example – red blood cells
Osmotic Pressure, PV =nRT where R is usual gas constant
Use osmotic pressure to determine molar masses of large molecules like proteins
Colloids: particles larger than ions/molecules but not large enough to settle
Tyndall effect: colloids scatter light
Soaps and surfactants: hydrophilic head and hydrophobic tail
