What is the common use of Calcium Hypochlorite?

• A. Fertilizing crops
• B. Disinfecting water
• C. Stabilizing pH levels
• D. Conditioning air

Answer: (B)

Calcium Hypochlorite is primarily recognized for its role in disinfecting water. It acts as a powerful chlorine-based compound that effectively kills bacteria, viruses, and other pathogenic organisms present in water, making it safe for consumption and use. The use of Calcium Hypochlorite in water treatment is crucial in maintaining public health, especially in areas where water quality is compromised or during emergencies such as natural disasters. This compound not only ensures the microbial safety of drinking water but is also employed in swimming pool sanitation to control the growth of harmful microorganisms.

The other options, while related to different applications, do not accurately represent the primary use of Calcium Hypochlorite. It is not typically used for fertilizing crops, although chlorine can play a role in some agricultural applications. Stabilizing pH levels is primarily handled by different compounds and buffers rather than Calcium Hypochlorite itself. Similarly, while conditioning air may involve various chemicals, Calcium Hypochlorite is not recognized as an agent for that purpose in air quality management.
