Calcium hypochlorite is primarily used for which purpose?

Calcium hypochlorite is primarily used for disinfecting water supplies due to its strong oxidative properties that help in killing bacteria, viruses, and other microorganisms present in the water. It is a widely recognized and effective water treatment chemical in the sanitation and public health sectors, as it can provide microbial control and ensure the safety of drinking water.

While calcium hypochlorite does have various applications, its role in water disinfection is paramount, which distinguishes it from the other options. The use of calcium hypochlorite as a mineral supplement or as a pH stabilizer is not common practice, and it does not function to regulate water temperature. Its main characteristic is as an efficient and reliable disinfectant, making it essential for maintaining clean and safe water supplies.
