The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement regarding potassium permanganate (KMnO4) and determine their validity. ### Step 1: Evaluate Statement 1 **Statement 1**: KMnO4 is not used as a primary standard substance. - **Explanation**: A primary standard is a substance that is pure, stable, and can be used to determine the concentration of a solution accurately. KMnO4 is not used as a primary standard because: - It cannot be obtained in a very pure form. - It reacts with traces of organic material and other reducing agents present in water, which can lead to inaccuracies in titration. - It decomposes in the presence of light, which affects its stability and purity. **Conclusion**: Statement 1 is correct. ### Step 2: Evaluate Statement 2 **Statement 2**: It is deliquescent in nature. - **Explanation**: A deliquescent substance is one that absorbs moisture from the air and dissolves in the absorbed water. Common examples include substances like sodium hydroxide and calcium chloride. However, potassium permanganate (KMnO4) does not exhibit this behavior. Instead, it can absorb moisture but does not dissolve to form a solution like typical deliquescent substances. **Conclusion**: Statement 2 is incorrect. ### Final Conclusion - **Statement 1** is correct: KMnO4 is not used as a primary standard substance. - **Statement 2** is incorrect: KMnO4 is not deliquescent in nature. Thus, the correct answer is that Statement 1 is true and Statement 2 is false.
