Osmotic pressure is: the pressure required to stop the flow of solvent from a region of high solute concentration to a region of low solute concentration. the pressure required to stop the rupture of the semipermeable membrane. the pressure required to reverse the flow of solvent through a semipermeable membrane during osmosis. the pressure required to stop the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration. None of these

Answer :

Answer:

the pressure required to stop the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration.

Explanation:

Osmosis is the movement of water (solvent molecule) from a region of low solute concentration to a region of high solute concentration via a semipermeable membrane.

Osmotic pressure is the pressure (force) applied to a given solvent in order to prevent it's movement via osmosis across a semipermeable membrane. Since, osmotic pressure is the pressure required to stop osmotic process, then it can be further defined as follows:

Osmotic pressure is the pressure required to stop the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration.
