Which of the following disinfecting compounds can be used full strength for disinfections?

Calcium hypochlorite is a powerful disinfectant that can be used in its full strength form for disinfection purposes. It is often used in water treatment and sanitation because it is effective at killing a wide range of pathogens, including bacteria, viruses, and protozoa.

When calcium hypochlorite is applied in its undiluted form, it provides a strong concentration of available chlorine, which enhances its germicidal properties. This makes it particularly useful in situations where immediate and effective disinfection is critical, such as in swimming pools, drinking water treatment, and in emergency situations where pathogen control is necessary.

In contrast, other disinfecting compounds mentioned may require dilution or have different operational protocols. Overall, the ability of calcium hypochlorite to serve as a full-strength disinfectant underscores its high efficacy and versatility in sanitation practices.
