Which substance is used to disinfect water because it can provide chlorine?

Answer and explanation

Correct answer: Bleaching powder

Bleaching powder, commonly represented as calcium oxychloride, releases chlorine or chlorine-containing disinfecting species in water. These substances oxidise and destroy many harmful microorganisms, making the water safer. Baking soda and washing soda are carbonates used for other purposes, while blue vitriol is copper sulfate and is not the standard school-level disinfectant for drinking-water treatment. Thus option A is correct.
