The correct Answer is:
To solve the question, we need to analyze both statements provided in the question and determine their validity and relationship. ### Step 1: Analyze Statement 1 **Statement 1:** "Osmotic pressure is a colligative property." - **Explanation:** Colligative properties are properties that depend on the number of solute particles in a solution, rather than the identity of those particles. Osmotic pressure is indeed a colligative property because it depends on the concentration of solute particles in a solution. The formula for osmotic pressure (π) is given by: \[ \pi = CRTI \] where: - \(C\) = concentration of the solution (moles of solute per liter of solution) - \(R\) = universal gas constant - \(T\) = temperature in Kelvin - \(I\) = van 't Hoff factor (number of particles the solute dissociates into) Thus, **Statement 1 is true.** ### Step 2: Analyze Statement 2 **Statement 2:** "Osmotic pressure is developed in a column due to osmosis." - **Explanation:** Osmotic pressure arises when a solvent moves through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. This movement creates pressure in the column of liquid. Hence, osmotic pressure is indeed developed due to the process of osmosis. Thus, **Statement 2 is also true.** ### Step 3: Determine the Relationship Between the Statements Now we need to check if Statement 2 correctly explains Statement 1. - **Analysis:** While both statements are true, Statement 2 does not provide a direct explanation for why osmotic pressure is classified as a colligative property. Statement 1 focuses on the dependence of osmotic pressure on the number of solute particles, while Statement 2 describes the phenomenon of osmosis itself. ### Conclusion Both statements are true, but Statement 2 does not explain Statement 1. Therefore, the correct answer is: **Both statements are true, but Statement 2 is not a correct explanation for Statement 1.** ### Final Answer **B**: Both statements are true, but Statement 2 is not a correct explanation for Statement 1. ---
