Two aqueous solutions are separated by a selectively permeable membrane that allows water to pass through but does not allow starch to pass through. Solution A is 10% starch and solution B is 5% starch. What will occur?
A) Water will diffuse from solution B to solution A.
B) Water will diffuse from solution A to solution B.
C) Starch will diffuse from solution B to solution A.
D) Starch will diffuse from solution A to solution B.
E) Both water and starch will diffuse from solution B to solution A.

Question

Water will move from the lower concentration of solute (solution B, 5% starch) to the higher concentration of solute (solution A, 10% starch) to try to equalize the solute concentration on both sides of the membrane, a process known as osmosis.
