Solution A with 10% concentration is separated via a semipermeable membrane from solution B with 20% concentration. What will be the direction of the movement of water molecules?
From Solution B to Solution A
From Solution A to Solution B
No net flow of water
None of the above is possible
When two solutions of different concentrations are separated from each other by a semipermeable membrane, the solvent from a low concentration solution begins to flow towards the one having a higher concentration. Hence, water will move from Solution A to Solution B.
Hence, the correct answer is option b.
