Question

Imagine two solutions separated by a selectively permeable membrane that is impermeable to glucose. On one side of the membrane, solution A contains 10 percent glucose and on the other side, solution B contains 25 percent glucose. Which of the following is true? a) Solution A is hypertonic relative to solution B. b) The concentration of water is greatest in solution B. c) Water will move from solution A to solution B. d) Glucose will diffuse from solution B to solution A

Answer 1

Answer:

C, Water will move from solution A to solution B.

Explanation:

Solution B is more concentrated than solution A and is thus said to be hypertonic to solution A. Since the membrane is impermeable to glucose but permeable to water, water molecules will keep moving from solution A to dilute solution B until an equilibrium is reached.

Hence, the correct option is C.
