peroxodisulfates
Peroxodisulfates are a group of chemical compounds with the general formula M2S2O8, where M is a cation, typically an alkali metal or ammonium. They are characterized by the presence of the peroxodisulfate anion, S2O8^2-. This anion contains a peroxide bond (-O-O-) linking two sulfate groups. Peroxodisulfates are strong oxidizing agents and are often encountered as white crystalline solids. They are soluble in water, and their solutions are acidic due to hydrolysis.
The most common peroxodisulfates are potassium peroxodisulfate (K2S2O8), sodium peroxodisulfate (Na2S2O8), and ammonium peroxodisulfate ((NH4)2S2O8). These
Peroxodisulfates have several important industrial applications. They are widely used as initiators for the polymerization of
