A membrane vesicle containing a solution with 0.25 M solute is placed into a solution containing 0.5M solute. You may assume that the membrane is impermeable to the solute and that the external solution is so large that you cannot change it’s solute concentration. What will happen to the membrane vesicle?

	A.	There will be no net osmosis
	B.	It will swell due to osmosis until it’s solute concentration reaches 0.5M
	C.	It will shrink due to osmosis until it’s solute concentration reaches 0.5M
	D.	It will shrink due to osmosis until it bursts

Expert Solution

1) Osmosis is the movement of water molecules from solution with higher water potential to lower water potential.

solutes decrease water potential, here the concentration of solute in the vesicle is less than that in the solution so water potential in the vesicle is higher than that in the outer solution, so water molecules from the vesicle move to the outer solution, as the volume of water decreases the concentration of solutes increases, water will move out of the vesicle till the concentration in the vesicle and outer solution is equal since water moves out the vesicle shrinks, so the answer is

c) It will shrink due to osmosis until it’s solute concentration reaches 0.5M

2) Osmosis is the movement of water molecules from solution with higher water potential to lower water potential.

solutes decrease water potential, here the concentration of solutes in the vesicle is greater than that in the solution so water potential in the vesicle is lower than that in the outer solution, so water molecules from the outer solution to the vesicle, as the volume of water increases the concentration of solutes decreases. water moves into vesicle till the concentration of solutes in the vesicle is 0.25 M

so the answer is c) It will swell due to osmosis until it’s solute concentration reaches 0.25M
