Figure 5.2 -The Solutions in the Two Arms of the U-Tube Shown

Multiple Choice

Figure 5.2
-The solutions in the two arms of the U-tube shown in Figure 5.2 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 are equal.After the system depicted in the figure reaches equilibrium,what changes are observed with respect to the concentrations of sugars?

A) The concentration of sucrose is equal in sides A and B,and the concentrations of glucose are unchanged.
B) The concentrations of glucose and sucrose are equal in sides A and B.
C) The concentration of glucose is equal in sides A and B,and the concentrations of sucrose are unchanged.
D) The water levels change,but the concentrations of glucose and sucrose in sides A and B are unchanged.
