What is the main reason for storing bleaching powder in a closed container?

Answer and explanation

Correct answer: Moisture and air can reduce its effectiveness

Bleaching powder is not perfectly stable during storage. Contact with atmospheric moisture and carbon dioxide can cause gradual decomposition and reduce the amount of available chlorine, which is responsible for much of its bleaching and disinfecting action. Keeping it in a tightly closed, dry container slows this deterioration. Therefore option A is correct; the other statements are chemically irrelevant.
