Which of the following best describes chlorine gas's nature?

Chlorine gas is highly toxic and can be fatal due to its potent oxidative properties and ability to react with moisture in the lungs, causing severe respiratory distress and damage. Its presence in water treatment processes is crucial for disinfection, but this also means that handling chlorine requires strict safety protocols to mitigate the risk of exposure. The inherent dangers of chlorine gas, including its potential to cause serious health effects even at low concentrations, make it a substance that must be treated with extreme caution. While it plays a vital role in ensuring water safety, understanding its toxic nature is essential for preventing accidents and ensuring safe working environments in water treatment facilities.
