What is the main reason for storing bleaching powder in a dry, closed container?
Answer and explanation
Correct answer: To reduce the loss of available chlorine
Bleaching powder works mainly because it contains available chlorine, which gives it bleaching and disinfecting properties. Moisture and exposure to air can cause gradual decomposition and reduce the amount of effective chlorine. A dry, tightly closed container limits this deterioration and preserves its activity. Thus option A is correct; the other choices describe unrelated or chemically incorrect changes.
