The solubilities of several solids as a function of temperature.
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 deviation from Raoult’s law negative deviation from Raoult’s law Ideal solution: Solute-solute, solvent-solvent and solute-solvent interactions are similar. (heptane, C7H16, and octane, C8H18) Figure 11.13
Freezing-Point Depression Solvent solidifies first – solution more concentrated Solvent molecules more separated – need to lower temp to freeze solution Figure 11.15
Osmosis - the diffusion of solvent through a semipermeable membrane from a more dilute solution to a more concentrated one } π Osmotic pressure (π) – pressure required to stop osmosis Semipermeable membrane - a membrane that allows some molecules to pass through but not others
(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
