Hydrogen peroxide is a colorless, odorless liquid widely used as a disinfectant and bleaching agent. It serves as a powerful antiseptic for minor cuts and wounds, helping to prevent infection. In addition to its medical applications, hydrogen peroxide is commonly used in household cleaning products to sanitize surfaces and remove stains. It also plays a role in industrial processes, including pulp and paper production and wastewater treatment. While generally safe in diluted forms, proper handling is essential, as concentrated hydrogen peroxide can be hazardous.
