Peroxy anion

WebSuperoxide, which is an anion radical, is produced by the one-electron reduction of molecular oxygen. In aqueous media, protonation of superoxide can form the uncharged hydroperoxyl radical (HOO•), which exhibits a p K a of 4.8, meaning that the anion radical form is by far the predominant species at physiological pH ranges. A second ... Several organic peroxyacids are commercially useful. They can be prepared in several ways. Most commonly, peracids are generated by treating the corresponding carboxylic acid with hydrogen peroxide: RCO2H + H2O2 ⇌ RCO3H + H2O A related reaction involves treatment of the carboxylic anhydride:
