Why is it proper to store bleaching powder in a dry and closed container?
Answer and explanation
Correct answer: To preserve its useful chlorine-related activity
Bleaching powder is useful because it contains available chlorine, which gives it bleaching and disinfecting action. Moisture and contact with air can gradually decompose or reduce the available chlorine, lowering the substance’s effectiveness. Keeping it in a dry, tightly closed container slows this deterioration. Therefore, option A is correct; the other options describe impossible changes unrelated to its storage.
