The solutions in the arms of this u-tube are separated at the bottom by a semipermeable membrane. the membrane is not permeable to glucose. side a is filled with a solution of 0.2 molar glucose and side b is filled with 0.5 molar glucose. initially the volume in both arms is the same. if you examine side a after three days, you should find

the volume of solution A would have decreased.

Explanation:

The concentration of glucose in solution B is higher than that of solution A. Hence, solution B is said to be hypertonic in relative to solution A, while solution A is said to be hypotonic relative to solution B.

Solution B thus has lower water potential than solution A. Consequently, water molecules moves from solution A to solution B till an equilibrium is established.

Hence, if side A is examined after three days, it will be discovered that the volume has decreased as a result of losing water to solution A.

im not in connections yet but i might can you some questions. what grade are you in?

idk let me see fdfdgdg
