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

Step 1
The U-tube is separated by a selectively permeable membrane. This means that only certain substances can pass through the membrane while others cannot. In this case, the membrane is permeable to sodium chloride but not to glucose. Show more…

An artificial "cell" consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution, the "environment," as shown below. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose. a. Draw solid arrows to indicate the net movement of solutes into and/or out of the cell. b. Is the solution outside the cell isotonic, hypotonic, or hypertonic? c. Draw a dashed arrow to show the net osmosis, if any. d. Will the artificial cell become more flaccid, more turgid, or stay the same? e. Eventually, will the two solutions have the same or different solute concentrations?
