Question

Suppose you have two identical solutions of glucose, A and B. The solutions are separated by a permeable membrane that will allow the movement of both glucose and water. You want to establish a concentration gradient so that more glucose in solution B will move into solution A.

How can you manipulate your experimental setup so that the glucose will move in that direction?

Answer 1

Add more water to A

Step-by-step explanation:

In order to establish a concentration gradient so that more glucose in solution B would move to A, more water would be needed in A.

Adding more water to A will reduce the glucose concentration of A and create a concentration gradient which will allow some glucose molecules to move from B to A in order for equilibrium to be re-established.
