Osmotic pressure - Wikipedia
WEBOsmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. [1] It is also defined as the measure of the tendency of a solution to take in its pure solvent by osmosis .

WEBNov 7, 2021 · Osmotic pressure is the minimum pressure that prevents solvent molecules (water) from flowing through a semipermeable membrane. In other words, it is the pressure of a solvent against a semipermeable membrane that seeks to equalize the concentration of a solution on both sides of the membrane.

WEBOsmotic pressure is defined as the minimum pressure applied to a solution to stop the flow of solvent molecules through a semipermeable membrane. The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in the solution.

WEBJul 12, 2023 · Osmotic pressure is a colligative property of solutions that is observed using a semipermeable membrane, a barrier with pores small enough to allow solvent molecules to pass through but not solute molecules or ions. The net flow of solvent through a semipermeable membrane is called osmosis (from the Greek osmós, meaning “push”).

WEB3 days ago · Osmotic pressure, the amount of force applied to a solution that prevents solvent from moving across a semipermeable membrane. Osmosis is the spontaneous flow of solvent from a solution with a lower concentration of solutes to a more concentrated solution, with flow occurring across a semipermeable

WEBWhen the pressure reaches a value that yields a reverse solvent transfer rate equal to the osmosis rate, bulk transfer of solvent ceases. This pressure is called the osmotic pressur e (\(\pi\)) of the solution. The osmotic pressure of a dilute solution can be determined in a similar way the pressure of an ideal gas is calculated using the ideal ...

WEBSep 10, 2024 · Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.
