A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disaccharide) and glucose (a monosaccharide) cannot pass. The membrane separates a 0.2-molar sucrose solution from a 0.2-molar glucose solution. With time, how will the solutions change

Since the two solutions are isotonic to one another, there would not be any change.

Explanation:

Molarity defines moles of the solute present in a solution. When two solutions have the same molarity, it means that they have the same moles of solutes in them. The presence of the same solute concentration makes the solutions isotonic. When two isotonic solutions are separated by a selectively permeable membrane, there would not be any movement of water by the process of osmosis. This is because osmosis occurs when two solutions of different solute concentration are separated by a selectively permeable membrane.
