Textbook Question
Chapter 7, Problem 8TYK
Use the following U-tube setup to answer questions 6 through 8.
The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 2.0 M sucrose and 1.0 M glucose. Side B is filled with 1.0 M sucrose and 2.0 M glucose.
After the system reaches equilibrium, what changes can be observed?
- a. The water level is higher in side A than in side B.
- b. The water level is higher in side B than in side A.
- c. The molarity of glucose is higher in side A than in side B.
- d. Both a and c have occurred.

The solutions in the two arms of the U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 2.0 M sucrose and 1.0 M glucose. Side B is filled with 1.0 M sucrose and 2.0 M glucose.
Initially, the solution in side A, with respect to that in side B, is what?
After the system reaches equilibrium, what changes are observed?
If a percent difference is a negative number, what does this tell us about the change in weight of the artificial cell? If the percent difference is a negative number, what does this tell us about the movement of water across the membrane?
Name the solution in which the relative concentration of water molecules and the solute on either side of the cell is same.
