What is one main use of bleaching powder?
Answer and explanation
Correct answer: Disinfection of water
A major use of bleaching powder is disinfecting drinking water. It reacts with water and produces chlorine-containing oxidising species that destroy many disease-causing microorganisms. This makes it valuable in public sanitation, although the amount used must be carefully controlled. It is not a cooking material, it is not added to increase acidity, and it is not used for melting metals. Thus option A correctly states its main use.
