If two solutions having different osmolarities are separated by a water-permeable membrane, will there be a change in the volume of the two compartments if the membrane is impermeable to solutes?

Will there be a change in the volume of the two compartments if the membrane is permeable to solutes?  Explain your answer.


I'm also new to this site so I'm going to try to do my best with working and figuring everything out on here.  :hey:

No. Any change of volume will be due to movement of solvent, for example water, while the solute is prevented from moving. Other result, the osmotic concentrations will become more balanced.
