Redox thermodynamics of atomic oxygen

The electron-transfer potentials for the reduction of ground-state atomic oxygen in water and in acetonitrile are summarized in Tables 2-3 and 2-4.jp addition, selected values for the reduction of the atomic oxygen in O3, HOIO3, HOOH, and HOCl are included. Because the oxygen atom in a water molecule is 

Likewise, the electron-transfer reduction of H2O (with uncharged hydrogen and oxygen atoms), which must overcome the stabilization of the strong O-H bonds, results in a -1 charge for oxygen rather than proton reduction 

In contrast, an equivalent charge-density change for the neutral oxygen in HO- is strongly favored  

Although the chlorine atom is among the strongest one-electron oxidants known,  

CI2 can transfer an electron from an HO because of the stabilization of the resulting HO- via bond formation with an H- from a second HO the latter product (O ) is stabilized via bond formation with a Cl- [AE°, 4-0.47 V (Eqs. 2-13 -2-15)1
