The pressure required to prevent the passage of water through a semi- permeable membrane from a region of low concentration of solutes to one of higher concentration, by osmosis.
May be defined as the hydrostatic pressure which must be applied to a solution on one side of a semipermeable membrane (solution B in the example for osmosis) in order to offset the flow of solvent (water) from the other side (solution A in the example for osmosis). It is a measure of the tendency or “strength” of water to flow from a region of low salt concentration (and conversely high water concentration) to regions of high salt concentration (and conversely low water concentration).
The pressure that develops or is present when two solutions of different concentrations are separated by a membrane that is permeable only to the solvent, osmosis.
The pressure required to stop the flow of a solvent through a membrane.
The pressure that must be applied to prevent the passage of a solvent. Only those solutes that cannot pass through a membrane can contribute to osmotic pressure.
Pressure between two solutions of different concentrations separated by a semipermeable membrane.
Part of the blood pressure that is due to plasma proteins; also known as blood colloid osmotic pressure.
The force with which a solvent, usually water, passes through a semipermeable membrane separating solutions of different concentrations. It is measured by determining the hydrostatic (mechanical) pressure that must be opposed to the osmotic force to bring the passage to a standstill.
The phenomenon of pressure arising when two solutions with varying concentrations are divided by a semipermeable membrane, like a cellular wall. This leads to the movement of the lower concentration solute across the membrane into the region with higher concentration (known as osmosis).
The pressure resulting from a solvent moving through a semipermeable membrane, flowing from a diluted solution into a more concentrated one.
