What is the scientific reason for storing bleaching powder in a dry closed container?
Answer and explanation
Correct answer: To reduce loss of available chlorine
The governing concept is the limited stability of bleaching powder, whose disinfecting and bleaching action depends on available chlorine. Moisture and prolonged exposure to air promote decomposition and reduce the amount of effective chlorine. A dry, tightly closed container slows this deterioration, so option A is correct. The purpose is not to convert bleaching powder into gypsum or sodium chloride, and taste has no relation to its storage or chemical activity.
