The primary use of chlorine is in the production of disinfectants and bleaching agents. It is widely utilized in water treatment processes to kill bacteria and pathogens, ensuring safe drinking water supplies. Chlorine is also a common component in household cleaning products and industrial processes, as well as in the manufacture of PVC (polyvinyl chloride) and other chemicals. Additionally, due to its strong oxidizing properties, chlorine plays a key role in chemical synthesis and is used in various applications, including pharmaceuticals, agriculture, and the production of plastics.
