The correct Answer is:
To solve the question, we need to analyze both statements provided. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The statement claims that "The freezing point of a solution decreases with a decrease in the amount of non-volatile solute." - According to colligative properties, when a non-volatile solute is added to a solvent, the freezing point of the solution decreases. This is because the presence of solute particles disrupts the formation of the solid phase, requiring a lower temperature to freeze the solution. - Therefore, if we decrease the amount of non-volatile solute, we are effectively increasing the freezing point of the solution, which contradicts the statement. Hence, **Statement 1 is incorrect**. 2. **Understanding Statement 2**: - The statement claims that "The freezing point of the solution is less than that of the solvent." - This is a fundamental principle of colligative properties. When a non-volatile solute is added to a solvent, the freezing point of the resulting solution is indeed lower than that of the pure solvent. This means that the freezing point of the solution is less than that of the solvent, confirming the statement. - Therefore, **Statement 2 is correct**. 3. **Conclusion**: - Since Statement 1 is incorrect and Statement 2 is correct, the correct option is that Statement 1 is incorrect but Statement 2 is correct. ### Final Answer: - **Option 3**: Statement 1 is incorrect, but Statement 2 is correct.
