Multiple choice

If a solution 'A' having an OP of 10 atm. is separated from another solution 'B' having an OP of 5 atm by a semipermeable membrane, what will happen?

  1. Solvent moves from B to A

  2. Solvent moves from A to B

  3. No movement of solvent occurs

  4. Movement of solute from A to B

A Correct answer
Explanation

Water moves from a region of lower osmotic pressure (higher water potential) to a region of higher osmotic pressure (lower water potential) across a semipermeable membrane. Therefore, solvent moves from B (5 atm) to A (10 atm).
