Discussion Activity - Osmosis At the beginning of an osmosis experiment involving a U-tube, sides A and B contain aqueous solutions with the following solutes. Side A: 2 M* glucose, 0.1 M NaCl; Side B: 1 M glucose, 0.2 M NaCl. The volumes on either side of the tube are the same and thus the level of the liquid is at the same height in both arms. A selectively permeable membrane at the bottom of the tube separates the two sides. It is permeable to water and to NaCl but not to glucose. The apparatus is allowed to stand for a number of days. *M = moles/liter The following questions refer to this experiment. For each of these items, select the most appropriate phrase from the key below: A. Both the statement and the reason are true. B. The statement is true, but the reason is false. C. The statement is false, but the reason is an accepted fact or principle having no bearing upon the statement. D. Both the statement and the reason are false.
