What is the purpose of adding small amounts of chlorine to water?

• A. To enhance flavor
• B. To improve the pH level
• C. To kill bacteria
• D. To soften the water

Answer: (C)

Adding small amounts of chlorine to water primarily serves the purpose of killing bacteria and other microorganisms. Chlorine is a powerful disinfectant that effectively destroys harmful pathogens, helping to ensure that the water is safe for consumption and use. This process is crucial in municipal water treatment facilities, where maintaining public health is a top priority. While some might think chlorine could improve flavor or adjust pH levels, its main role is in sanitation. The addition of chlorine does not soften water, which is a different process involving the removal of calcium and magnesium ions. Overall, the use of chlorine in water treatment is a critical step in providing clean and safe drinking water.
