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.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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.

    “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].”
  • Superoxide oxidises few biological compounds.

    “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.
