NEET Chemistry Raoult's Law MCQ Question
Which of the following statements about osmotic pressure and solutions is correct?
Osmotic pressure is a colligative property that can be used to determine the molar mass of solutes.
Isotonic solutions have different osmotic pressures and will not exhibit osmosis.
Osmotic pressure is always lower than atmospheric pressure in all solutions.
Osmotic pressure increases with decreasing temperature in a solution.
Correct Answer
Detailed Explanation
Osmotic pressure is indeed a colligative property that is particularly useful for determining the molar mass of solutes, especially biomolecules, as mentioned in Chunk 2. Isotonic solutions have the same osmotic pressure, contradicting option B, while C and D are incorrect statements regarding osmotic pressure behavior.
