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 occur 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.

Answer:

Option C

Explanation:

Image for the question is attached here

Solution

It is given that the membrane is permeable to both salt and water.

Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.

As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.

Thus water will move from side A to side B and Salt will move from side B to side A.

Hence, option C is correct
