Osmotic pressure is:
A)the pressure required to stop the flow of solvent from a region of high solute concentration to a region of low solute concentration.
B)the pressure required to stop the rupture of the semipermeable membrane.
C)the pressure required to reverse the flow of solvent through a semipermeable membrane during osmosis.
D)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.
E)none of the above

Question

Quizplus · Accepted Answer

Osmotic pressure is the pressure that must be applied to prevent the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration. This occurs due to the tendency of solvent molecules to equalize the concentration of solute on either side of the membrane during osmosis. The higher the concentration of solute on one side of the membrane, the greater the pressure required to prevent the flow of solvent. Thus, choice D is the correct option.
