Osmotic pressure of the solution can be increased by_________________?
Correct answer: C. None of these
- A. Decreasing its temperature
- B. Increasing the volume of the vessel containing the solution
- C. None of these
- D. Diluting the solution
Explanation
Osmotic pressure follows π = iCRT, so it increases with temperature or concentration. Decreasing temperature, increasing vessel volume at fixed solute amount, and dilution all reduce concentration or temperature, so none of the listed changes increases it.
