The Solutions in the Two Arms of This U-Tube Are

Multiple Choice

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 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 on both sides are equal. Which of the following will be true when the system illustrated above reaches equilibrium?

A) The concentration of sucrose on side A will be greater than the concentration of sucrose on side B.
B) The water level will be higher in side A than in side B.
C) The water levels will be unchanged.
D) The water level will be higher in side B than in side A.
