The Solutions in the Arms of a U-Tube Are Separated

Question 10

Multiple Choice

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.

Initially, the volume in both arms is the same. Refer to the figure to answer the following questions.    -If you examine side A after three days, you should find A)  a decrease in the concentration of NaCl and glucose and an increase in the water level. B)  a decrease in the concentration of NaCl, an increase in water level, and no change in the concentration of glucose. C)  no net change in the system. D)  a decrease in the concentration of NaCl and a decrease in the water level. E)  no change in the concentration of NaCl and glucose and an increase in the water level.
