Chloramines are ____?

Chloramines are ____?

• A. Free Chlorine
• B. Combined Chlorine
• C. Oxidized Chlorine
• D. Chloride Ions

Answer: (B)

Chloramines are a form of chlorine bound to nitrogen, created when chlorine used for disinfection reacts with ammonia or other nitrogen-containing compounds in the water. This makes them a combined chlorine species rather than free chlorine, which exists as hypochlorous acid and hypochlorite. Chloramines (monochloramine, dichloramine, and trichloramine) are more stable and persist longer in the system, but they’re less aggressive as disinfectants than free chlorine. They’re commonly used to maintain a residual disinfectant in distribution systems and to reduce disinfection byproducts. Chloride ions, by contrast, are simply chlorine in a reduced form with no disinfection activity.
