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 and water 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. Side A Initial setup Side B 0.4 M glucose 0.5 M NaCl 0.8 M glucose 0.4 M NaCl Membrane If you examine side A after three days, you should find a decrease in the concentration of NaCl and glucose and an increase in the water level. a decrease in the concentration of NaCl, an increase in water level, and no change in the concentration of glucose. no net change in the system. a decrease in the concentration of NaCl and a decrease in the water level. no change in the concentration of NaCl and glucose and an increase in the water level.

Step 1
This means that sodium chloride and water can move freely across the membrane, but glucose cannot. Second, the concentrations of glucose and sodium chloride are different on the two sides of the membrane. On side A, the concentration of glucose is lower (0.4 M) Show more…

The solutions in the two arms of the U-tube shown in the figure below are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is half-filled with a solution of 2 M sucrose and 1 M glucose. Side B is half-filled with 1 M sucrose and 2 M glucose. Initially, the liquid levels are equal. After the system depicted in the figure reaches equilibrium, what changes are observed with respect to the concentrations of sugars? 1) The concentration of sucrose is equal in sides A and B, and the concentrations of glucose are unchanged. 2) The water levels change, but the concentrations of glucose and sucrose in sides A and B are unchanged. 3) The concentration of glucose is equal in sides A and B, and the concentrations of sucrose are unchanged. 4) The concentrations of glucose and sucrose are equal in sides A and B.
