Question

If $$0.1\,M$$  solution of glucose and $$0.1\,M$$  solution of urea are placed on two sides of the semipermeable membrane to equal heights, then it will be correct to say that

A. there will be no net movement across the membrane  
B. glucose will flow towards urea solution
C. urea will flow towards glucose solution
D. water will flow from urea solution to glucose
Answer :   there will be no net movement across the membrane
Solution :
As both the solutions are isotonic hence there is no net movement of the solvent through the semipermeable membrane between two solutions.
