Reactivity of HO2/O− 2 radicals in aqueous solution
Abstract
Kinetic data for the superoxide radical (HO2⇄O−2 +H+, pK=4.8) in aqueous solution have been critically assessed. Rate constants for reactions of O−2 and HO2 with more than 300 organic and inorganic ions, molecules and other transient species have been tabulated.

In the citing paper
“Superoxide absorbs light in the ultraviolet range with a maximum at 245 nm and an extinction coefficient of 2350 M−1 cm−1, whereas hydroperoxyl absorbs at 225 nm with an extinction coefficient of 1400 M−1 cm−1 [20].”

In the citing paper
“Superoxide oxidises few biological compounds [20], and this is due to the following reasons:-Its anionic charge which limits its reactivity to compounds with electron-rich centres [63].-Its facility for spontaneous dismutation [64].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
