question 31

Multiple Choice

Figure 5.3
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, side A

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