NEET Chemistry Colligative Properties MCQ Question
Consider a diagram showing a U-tube with a semipermeable membrane separating a pure solvent on one side and a solution on the other. Which statement correctly describes the osmotic pressure in this scenario?
Osmotic pressure is applied to the solution side to prevent solvent flow.
Osmotic pressure causes the solvent to flow into the solution side without resistance.
Osmotic pressure equalizes the concentration of solute between both sides.
Osmotic pressure increases the boiling point of the solvent.
Correct Answer
Detailed Explanation
The NCERT context states that excess pressure equal to the osmotic pressure must be applied on the solution side to prevent osmosis, ensuring the solvent does not flow across the membrane.
