Final answer:
Chlorine can easily inactivate viruses in water disinfection.
Step-by-step explanation:
Water disinfection agents such as chlorine can easily inactivate viruses. Chlorine compounds, including sodium hypochlorite, chloramines, and chlorine dioxide, are commonly used for water disinfection. Chlorine gas is commonly used in municipal drinking water and wastewater treatment plants to produce a strong oxidant called hypochlorous acid, which inactivates viruses and other harmful organisms.
