A beaker contains two solutions of salt dissolved in water. The two solutions have different concentrations of salt (measured by molarity, M) and are separated by a membrane that is permeable to both salt and water. The salt and water will move through the membrane by diffusion. Which statement is true about the diffusion of these solutions? There will be a net movement of water from side A to side B and no movement of salt. There will be a net movement of salt from side B to side A and net movement of water from side A to side B. There will be a net movement of both salt and water from side B to side A. There will be a net movement of salt from side A to side B and no movement of water.

There will be a net movement of salt from side B to side A and net movement of water from side A to side B

Explanation:

Hello,

In this case, the "driving force" is which causes the movement of the salt from side B to side A as long as a concentration difference is present, thus, the matter tends to move from higher to lower concentrations, assuming that the salt content is higher in side B. On the other hand, the water moves conversely, since the water content is is higher in side A and the whole system looks for the equilibrium (same concentration in the system), considering the presence of the semipermeable membrane.

Best regards.
