Abstract
Acid dissociation constants of OH and HO2 were measured over a range of temperature and give heats of ionization of 10 and 0 kcal mol–1 respectively. These values lead to ΔH°f of (O–2)aq and (O–)aq=–8(±2) and 9(±2) kcal mol–1 respectively. Solvation energies of O–2 and O– are estimated to be 94 and 113 kcal mol–1 and the E° of the couples O2/O–2, O/O–, –0.19 and 1.64 V respectively.
