The correct Answer is:
To analyze the given statements, we will evaluate each statement separately and determine their validity based on the chemistry involved. ### Step 1: Evaluate Statement 1 **Statement 1**: In dilute solution of strontium ions, yellow precipitate of `SrCrO4` is formed with `CrO4^(2-)` ions. 1. **Reaction**: When strontium ions (`Sr^(2+)`) react with chromate ions (`CrO4^(2-)`), the expected reaction is: \[ Sr^{2+} + CrO_4^{2-} \rightarrow SrCrO_4 \text{ (s)} \] 2. **Solubility**: However, `SrCrO4` is known to be appreciably soluble in water, especially in dilute solutions. This means that even though a reaction occurs, the product does not form a stable precipitate under these conditions. 3. **Conclusion**: Thus, the statement that a yellow precipitate is formed is incorrect. Therefore, **Statement 1 is false**. ### Step 2: Evaluate Statement 2 **Statement 2**: The `SrCrO4` precipitate is appreciably soluble in water, therefore, no precipitation occurs when water is taken in large quantity. 1. **Solubility**: As established, `SrCrO4` is indeed appreciably soluble in water. This means that if we were to add a large quantity of water to the solution containing `SrCrO4`, it would dissolve rather than precipitate out. 2. **Conclusion**: Therefore, the statement that no precipitation occurs when water is added in large quantities is correct. Thus, **Statement 2 is true**. ### Final Conclusion - **Statement 1** is false. - **Statement 2** is true. Based on the evaluations, the correct answer is that Statement 1 is false and Statement 2 is true. Therefore, the answer is **D**. ---
