Textbook Question
Chapter 7, Problem 6TYK
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.
Initially, the solution in side A, with respect to that in side B,
- a. has a lower solute concentration.
- b. has a higher solute concentration.
- c. has an equal solute concentration.
- d. is higher in the tube.
