The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement one by one and determine whether they are true or false. ### Step 1: Evaluate Statement 1 **Statement 1:** At definite temperature, the solubility of a solute is fixed. - **Explanation:** The solubility of a solute in a solvent is indeed dependent on temperature. At a specific temperature, a solute can dissolve in a solvent up to a certain limit, known as its solubility. Beyond this limit, no more solute can dissolve, leading to a saturated solution. Therefore, at a definite temperature, the solubility of a solute is fixed. - **Conclusion:** This statement is **True**. ### Step 2: Evaluate Statement 2 **Statement 2:** When an azeotropic mixture is distilled, its composition remains the same. - **Explanation:** An azeotropic mixture is a mixture of two or more liquids that has a constant boiling point and composition throughout the distillation process. When an azeotropic mixture is distilled, both the liquid and vapor phases maintain the same composition, meaning that the ratio of the components does not change during the distillation. This characteristic makes azeotropic mixtures difficult to separate by simple distillation. - **Conclusion:** This statement is **True**. ### Step 3: Evaluate Statement 3 **Statement 3:** Vapour pressure is a colligative property. - **Explanation:** Vapour pressure itself is not classified as a colligative property. However, the relative lowering of vapour pressure is a colligative property. Colligative properties depend on the number of solute particles in a solution rather than the identity of the solute. The addition of a non-volatile solute to a solvent decreases the vapour pressure of the solvent, which is described by the concept of relative lowering of vapour pressure. Therefore, while the effect on vapour pressure is a colligative property, vapour pressure itself is not. - **Conclusion:** This statement is **False**. ### Final Evaluation - **Statement 1:** True - **Statement 2:** True - **Statement 3:** False ### Final Answer The correct option based on the evaluation of the statements is **True, True, False**.
