It is widely utilized in water treatment facilities to disinfect drinking water and swimming pools due to its strong chlorine content, which effectively kills bacteria, viruses, and other pathogens.

The versatility and effectiveness of bleaching powder make it a valuable chemical in both industrial and domestic applications.
