Question:

The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same. Refer to the figure to answer the following questions.

At the beginning of the experiment,

A) side A is hypertonic to side B.

B) side A is hypotonic to side B.
C) side A is hypertonic to side B with respect to glucose.
D) side A is hypotonic to side B with respect to sodium chloride.

E) side A is isotonic to side B.

Answer:
B) side A is hypotonic to side B.
