  • Colligative properties

    properties directly proportional to the solute concentration in the solvent (water)

  • Ideal solution

    no change in physical properties other than dilution

  • Real solutions

    change in physical properties occur

  • 290-310 mOsmol

    What is the body osmolarity?

  • Hyper-osmolar

    results in crenation (shrinkage of cells)

  • Hypo-osmolar

    results in hemolysis of the cell (swelling)

  • Iso-osmolar

    no gain or loss of water by the cells

  • Hypertonic solution

    a solution that has a higher solute concentration than another solution. Water particles will move out of the cell, causing crenation.

  • Isotonic solution

    a solution that has the same solute concentration as another solution. There is no net movement of water particles, and the overall concentration on both of sides of the cell membrane remains constant.

  • Hypotonic solution

    a solution that has a lower solute concentration than another solution. Water particles will move into the cell, causing the cell to expand and eventually lyse.

  • biologic compatibility and equal osmotic pressure

    isotonic =

  • only equal osmotic pressure

    isoosmotic=

  • Freezing point depression

    colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The freezing points of solutions are all lower than that of the pure solvent and is directly proportional to the molality of the solute.

  • Boiling point elevation

    describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.
