Final answer:
Bromine is sometimes used as a disinfectant in swimming pools instead of chlorine.
Step-by-step explanation:
Bromine is sometimes used as a disinfectant in swimming pools instead of chlorine. Chlorine is commonly used as a disinfectant in drinking water supplies and public swimming pools. However, bromine is starting to replace chlorine in pools due to its higher effectiveness. Unlike chlorine, bromine does not react with the proteins in human hair and skin, reducing the chlorine aroma associated with swimming pools.
