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

Multiple Choice

The solutions in the two arms of a 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. When the system illustrated above reaches equilibrium, the sugar concentrations on both sides of the U-tube will be ________.

A) 2 M sucrose, 1 M glucose
B) 1 M sucrose, 2 M glucose
C) 1 M sucrose, 1 M glucose
D) 1.5 M sucrose, 1.5 M glucose
