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

Question 32
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. img In the U-tube experiment illustrated above, which of the following statements correctly describes side B at equilibrium? A) The concentration of NaCl and glucose will decrease, and the water level will increase. B) The concentration of NaCl will increase, the concentration of glucose will decrease, and the water level will increase. C) The concentration of NaCl will increase, the concentration of glucose will decrease, and the water level will decrease. D) The concentration of NaCl and glucose will increase, and the water level will decrease.
