osmotic pressure

osmotic pressure
osmotic pressure n the pressure produced by or associated with osmosis and dependent on molar concentration and absolute temperature: as
a) the maximum pressure that develops in a solution separated from a solvent by a membrane permeable only to the solvent
b) the pressure that must be applied to a solution to just prevent osmosis

* * *

the pressure required to stop osmosis through a semipermeable membrane between a solution and pure solvent; it is proportional to the osmolality of the solution and also to other colligative properties of the solution, including freezing point depression, vapor pressure depression, and boiling point elevation. Symbol π.
