The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
The following table provides the reduction potentials of the indicated reducing agent at 25 °C. For example, among sodium (Na), chromium (Cr), cuprous (Cu +) and chloride (Cl −), it is Na that is the strongest reducing agent while Cl − is the weakest; said differently, Na + is the weakest oxidizing agent in this list while Cl is the strongest.

The reduction potential is a measure of the tendency of the oxidizing agent to be reduced. Its value is zero for H + + e − → 1 ⁄ 2 H 2 by definition, positive for oxidizing agents stronger than H + (e.g., +2.866 V for F 2) and negative for oxidizing agents that are weaker than H + (e.g., −0.763V for Zn 2+).

Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactive series. However, they are only valid for standard conditions: in particular, they only apply to reactions in aqueous solution. Even with this proviso, the electrode potentials of lithium and ...
An oxidizing acid is a Brønsted acid that is a strong oxidizing agent. Most Brønsted acids can act as oxidizing agents, because [dubious – discuss] the acidic proton can be reduced to hydrogen gas. Some acids contain other structures that act as stronger oxidizing agents than hydrogen ions. Generally, they contain oxygen in their anionic ...
However, in contrast to red fuming nitric acid (HNO 3 /N 2 O 4), or concentrated nitric acid (HNO 3), nitrate dissolved in aqueous solution at neutral or high pH is only a weak oxidizing agent and is stable under sterile, or aseptic, conditions, in the absence of microorganisms. To increase its oxidation power, acidic conditions and high ...
Bromine and iodine are relatively weak oxidizing agents, so fewer oxobromides and oxoiodides are known. Structures for compounds with d 0 configuration are predicted by VSEPR theory . Thus, CrO 2 Cl 2 is tetrahedral , OsO 3 F 2 is trigonal bipyramidal , XeOF 4 is square pyramidal and OsOF 5 is octahedral . [ 18 ]
