Sodium hypochlorite (NaOCl), commonly known as bleaching liquid, is a pale greenish-yellow solution renowned for its powerful disinfectant and bleaching properties. Produced by dissolving chlorine gas in a sodium hydroxide solution, it serves as a highly effective oxidizing agent. In household cleaning, it is used to disinfect surfaces, remove stains, and sanitize areas prone to microbial contamination. Municipal water treatment facilities employ sodium hypochlorite to disinfect drinking water and treat wastewater, ensuring safety and reducing pollutants. In industrial applications, it is essential for bleaching textiles and paper, and in chemical manufacturing processes. The healthcare sector uses it for surface disinfection and wound care, while the food industry utilizes it to sanitize preparation surfaces and equipment, maintaining hygiene and preventing contamination. Despite its widespread use, handling sodium hypochlorite requires caution due to its corrosive nature and potential to release harmful chlorine gas.
