What is the most widely used chemical to destroy microorganisms?

• A. Bromine
• B. Hydrogen peroxide
• C. Purple iodine
• D. Chlorine

Answer: (D)

Chlorine is the most widely used chemical for the destruction of microorganisms due to its strong oxidizing properties and effectiveness at various concentrations and forms. It is a powerful disinfectant that can quickly kill bacteria, viruses, and other pathogens in water systems, making it indispensable in both potable water treatment and wastewater management processes. The use of chlorine is advantageous because it leaves a residual effect in the water, providing ongoing protection against recontamination after treatment. This characteristic is vital for maintaining safe drinking water standards and for ensuring that treated wastewater does not pose a risk when released back into the environment. Chlorine can be applied in several forms, such as chlorine gas, sodium hypochlorite, and calcium hypochlorite, making it versatile for different applications. Its long-standing usage in water treatment processes is supported by extensive research and regulatory approval, solidifying its role as a critical component in public health safety.
