What is produced when chlorine reacts with ammonia?

• A. Chlorine dioxide
• B. Sodium hypochlorite
• C. Chloramine
• D. Calcium hypochlorite

Answer: (C)

When chlorine reacts with ammonia, chloramine is produced. This reaction typically occurs during the disinfection process in water treatment facilities, where chlorine is used to effectively kill pathogens and ammonia can be present as a contaminant or additive. Chloramines are a group of chemical compounds that result from the reaction of chlorine with ammonia derivatives. They are formed as a way to maintain residual disinfectant levels in the water while reducing the formation of harmful disinfection byproducts, which can occur when using chlorine alone. Using chloramines as a secondary disinfectant in water systems can also lead to less chlorine taste and odor in the drinking water compared to chlorine alone. This method is particularly useful in systems where long-lasting disinfection is desired, as chloramines are more stable and can remain effective over longer distances in distribution systems. Understanding this reaction is crucial for water treatment operators, as using chloramine can influence water quality and safety in the distribution system.
