General description
Potassium persulfate is a water-soluble inorganic salt that releases oxygen and exhibits a strongly exothermic reaction. It is stable at room temperature but decomposes at high temperatures. Potassium persulfate is commonly used as an oxidant and in the polymerization of numerous monomers, mainly in the field of hydrogel synthesis.
