The beaker in the illustration below contains two solutions of salt with different concentrations (measured by molarity, M). The two solutions are separated by a membrane that is permeable to both salt and water.

Which of the following will you observe immediately in this container?

A) Net diffusion of water from B to A and of salt from A to B.

B) Net diffusion of salt from B to A, but no net diffusion of water.

C) Net diffusion of water from A to B and of salt from B to A.

D) No net diffusion of water or salt across the membrane.

E) Diffusion of salt across the membrane, but not of water.

F) Net diffusion of water across the membrane, but not of salt.

Either option A or option C

Explanation:

Here if the concentration of the two solution was given then it would have been very easy to interpret that which solution will start moving to the other compartment.

Here there can be two cases - salt from the solution which has higher salt concentration, will start moving to the solution having lower salt concentration and the same will happen for water which shall start moving from region of high concentration to region of lower concentration.

Thus, two option i. e. option A and option C are correct.
