K2O2SO2
Potassium peroxodisulfate, with the chemical formula K2O2SO2, is an inorganic compound. It is also known as potassium persulfate. It is a white, crystalline solid that is soluble in water. This compound is a powerful oxidizing agent. Its primary uses are in bleaching, cleaning, and as an initiator for polymerization reactions. Potassium peroxodisulfate is often employed in hair bleaching formulations and as a component in laundry detergents for stain removal. In industry, it plays a role in the production of plastics and other polymers. It is typically produced by the electrolysis of potassium bisulfate or potassium sulfate solutions. When heated, potassium peroxodisulfate decomposes, releasing oxygen and sulfur dioxide. Care should be taken when handling this substance due to its oxidizing properties, as it can react vigorously with combustible materials. It is important to store it in a cool, dry place away from incompatible substances.
