Astudent put together the experimental set-up shown below. the selectively permeable membrane is permeable to water, but not to the solute shown.

look at figure 7-10. describe the movement of water in the experimental set-up. what will happen to the concentration of water over time?

Water will move from part A to part B till equilibrium is reached

Explanation:

It is given that selectively permeable membrane will allow water to pass through it but not the solute.  

Thus, water from the region of higher concentration will start moving towards the region of low concentration i.e from side A to side B. This process of transfer will continue till the concentration of water on both the sides become equal or till the equilibrium is reached.
