| Term | Definition |
|
Osmolarity |
the concentration of all solute particles in a solution. |
|
Osmosis |
the movement of water across a semi-permiable membrane from an area of high concentration of non-penetrating particles to an area of low concentration of non-penetrating particles |
|
Tonicity |
Defined by the nature of the solute that either prevents or promotes osmosis from occuring to a cell |
|
Requirements for Isotonic Solution |
(1) The ECF must have the same osmolarity as the ICF. (2) the solute must be non-penetrating |
