Assertion : Osmotic pressure is a colligative property. Reason : Osmotic pressure depends only on the number of particles dissolved in solution.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Colligative properties of a solution, like osmotic pressure and freezing point depression, depend solely on the number of solute particles, regardless of the solute's identity, as long as the particles remain undissociated and undergo no chemical changes in the solution. So option (1) is correct.

The swelling in feet and ankles of an aged person due to sitting continuously for long hours during travel, is reduced by soaking the feet in warm salt water. This is because of:
1 Edema
2 Diffusion
3 Reverse osmosis
4 Osmosis
Explanation:
Osmosis is responsible for the swelling in feet and ankles of an aged person due to sitting continuously for long hours during travel.

Assertion : If red blood cells were removed from the body and placed in pure water, pressure inside the cells increases. Reason : The concentration of salt content in the cells increases.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
When red blood cells are placed in pure water, water molecules enter into red blood cells due to osmosis and salt concentration in the cell decreases. Due to water molecules entering into red blood cells, hydrostatic pressure increases. So, assertion is correct, but reason is false.
