Question

The two chambers, A and B, containing solution are separated by a semipermeable membrane.
In which direction will osmosis occur?

• A. A $\to$ B
• B. B $\to$ A
• C. Osmosis will not occur
• D. Cannot be determined

Answer 1

The correct option is B B $\to$ A

• Osmosis is a process in which solvent passes through a semipermeable membrane from an area of less concentration to the area of more concentration of solute.
• In the given example, chamber A contains a high concentration of solutes as compared to chamber B. Hence, the solution will move from B to A through the semipermeable membrane until an equilibrium is attained.

Thus, the correct answer is 'B → A.'
