Henry’s law: C = kP (figure 11.5 in Zumdahl 8ed)

The vapor pressure is the force exerted by the gas released by a liquid or solid substance in a closed container.
Vapor pressure is a relative measure of the tendency to evaporate (volatility), depends on the nature of the substance and ambient temperature.

ideal liquid–liquid solution positive deviationfrom Raoult’s law
negative deviationfrom Raoult’s law
Ideal solution: Solute-solute, solvent-solvent and solute-solvent interactions are similar.

Freezing-Point Depression
Figure 11.15
Solvent solidifies first – solution more concentrated
Solvent molecules more separated – need to lower temp to freeze solution

Osmosis - the diffusion of solvent through a semipermeable membrane from a more dilute solution to a more concentrated one
Semipermeable membrane - a membrane that allows some molecules to pass through but not others
π }Osmotic pressure (π) – pressure required to stop osmosis

(a) Isotonic - osmotic pressures being equal (b) Hypotonic - osmotic pressure lower than that in the cell (c) Hypertonic - osmotic pressure higher than that in the cell
