Question

Two chambers, A and B, containing solutions are separated by a semipermeable membrane.

(g) What will be the direction of the movement of water when two solutions with Ψw = 0.2 MPa and Ψw = 0.1 MPa are separated by a selectively permeable membrane?

Answer 1

1) When a membrane is permeable to only a particular type of molecules.

2) Movement of water is from higher water potential to lower water potential. Thus water will move from the solution having 0.2 MPa water potential to a solution having 0.1 MPa water potential.
