What is "persulfate"

alt. (context inorganic chemistry English) Any of several oxyanions (and their associated salts) that have peroxide units linked to one or more sulfur atoms n. (context inorganic chemistry English) Any of several oxyanions (and their associated salts) that have peroxide units linked to one or more sulfur atoms

The term persulfate (sometimes known as peroxysulfate) refers to ions or compounds containing the anions or . The anion contains one peroxide group per sulfur center, whereas in , the peroxide group bridges the sulfur atoms. In both cases, sulfur adopts the normal tetrahedral geometry typical for the S(VI) oxidation state. These salts are strong oxidizers.
