Oxidation Chemistry
The persulfate anion is the most powerful oxidant of the peroxygen family of compounds. The electromotive force data listed below compares three commonly used peroxygens:
Many metals are oxidized by persulfate to form soluble metal sulfates, for example, copper:
Under certain circumstances, hydrolysis of the persulfate anion will yield the bisulfate anion and hydrogen peroxide a kinetically faster oxidant than persulfate:
Another reaction of note is the acid-catalyzed hydrolysis of persulfate to form peroxymonosulfate anion. Fast, high-temperature, acid hydrolysis followed by thermal quenching will yield solutions of peroxymonosulfate:
The resulting solution is a useful replacement for Caro's acid, H2 SO5 and potassium caroate, KHSO5. Reactions at different pH:
