Used primarily as a disinfectant and bleaching agent in laboratories and industrial settings. Commonly applied in water treatment to sanitize drinking water and wastewater by killing bacteria, viruses, and other pathogens. Also utilized in the food industry for surface sanitation and equipment cleaning to maintain hygiene standards. In healthcare environments, it serves for decontaminating surfaces and sterilizing instruments. Its accurate concentration in standard solution form makes it ideal for titration and analytical chemistry to determine oxidizing capacity in samples.
