What are halogen compounds primarily used for in potable water systems?

• A. Bromine as a disinfectant
• B. Chlorine to clean
• C. Both bromine and chlorine
• D. Chlorine and iodine for purification

Answer: (C)

Halogen compounds, particularly chlorine and bromine, are primarily used for disinfecting potable water systems. Chlorine is the most commonly used halogen due to its effectiveness in eliminating a wide range of pathogens, including bacteria and viruses. It works by breaking down the cellular structure of microorganisms, ensuring the water is safe for consumption. Bromine also serves as an effective disinfectant, particularly in specific contexts such as swimming pools and hot tubs, where water temperature and pH levels can diminish chlorine's effectiveness. It is often chosen for its stability in warm water environments. The correct answer acknowledges both chlorine and bromine's roles in disinfection, reflecting the comprehensive use of these halogen compounds in various water treatment applications. Although options that mention only one halogen may highlight its significance, they do not cover the full spectrum of halogen use in potable water systems.
