Colligative properties | Properties that depend only on the amount of solute present, not on the identity of the solute particles in a solution |
Vapor pressure lowering | due to solute-solvent intermolecular attractions, higher concentrations of nonvolatile solutes make it harder for solvents to escape to the vapor phase |
Raoult's Law | Shows that the addition of a nonvolatile solute simply dilutes the solvent |
Boiling point elevation | Occurs at a temperature where the vapor pressure of the liquid equals the atmospheric pressure |
Freezing point depression | When a nonvolatile solute is dissolved in a pure solvent (i.e. water), the freezing point of the resulting solution is lowered |
Osmotic pressure (π) | The pressure that must be applied to a solution to stop osmosis |
Osmosis | The flow of solvent into a solution through a semipermeable membrane from a region of low solute concentration to an area of high solute concentration |
Semipermeable membrane | A semi-porous membrane that selectively allows solvent but not solute molecules to pass through |
Hypertonic | If the solute concentration outside the cell is greater than that inside the cell |
Crenation | The shrinkage of cells that occurs when the surrounding solution is hypertonic |
Hypotonic | If the solute concentration outside the cell is less than that inside the cell |
Hemolysis | The rupture or destruction of a cell when the solution is hypotonic |
Reverse osmosis | The process in which a solvent is forced through a semipermeable membrane, leaving a more concentrated solution behind |
Tyndall effect | The phenomenon of scattering of light particles |
