Two solutions of differing glucose concentration are placed in a container separated by a selectively permeable
membrane that restricts large molecules like glucose, but allows the free diffusion of water. What will be the glucose
concentration in the container after dynamic equilibrium has been reached?
a. The water molecules will be evenly distributed in the container, with more glucose molecules on one side than
the other.
b. The volumes of the solution will be different, with a higher volume on the side that originally contained the
higher concentration of glucose.
c. The volumes of the solution will be different, with a lower volume on the side that originally contained the
higher concentration of glucose.
d. The glucose concentration of the two solutions will be identical on both sides of the membrane, but the
volumes will remain unchanged.
e. The volume and concentrations will be unchanged on both sides of the membrane.
