WebRedox reactions are identified per definition if one or more elements undergo a change in oxidation number. This is not a redox reaction, since oxidation numbers remain unchanged for all elements. This is a redox reaction. Gallium is oxidized, its oxidation number increasing from 0 in Ga ( l) to +3 in GaBr 3 ( s ). The reducing agent is Ga ( l ). WebApr 11, 2024 · In recent years, the redox reaction of iron in subsurface sediments was found to produce ·OH naturally, even in dark conditions without the presence of exogenous hydrogen peroxide.
