Q1. The solutions in the two arms of the U-tube shown below 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, liquid levels on both sides are equal.
At first, in terms of tonicity, the solution in side A with respect to that in side B is
