Name: Potassium Persulfate
SKU: 0

Potassium Persulfate is an important inorganic peroxide with the chemical formula K₂S₂O₈. It appears as white crystalline powder or granules, odorless, and readily soluble in water. As a strong oxidizing agent, it decomposes when heated to release oxygen. It is widely used as a polymerization initiator, bleaching agent, etching agent, and in chemical synthesis.
