WebOxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers ). H+1 2O-1 2 + … WebOct 8, 2024 · In both reactions $\ce{H2O2}$ is oxidized by the more powerfull oxidizers permanganate ($\ce{KMnO4-}$) and dichromate ($\ce{Cr2O7^2-}$). Whether or not oxygen is produced depends on the actual reaction and not necessarily on pH. A rule is that when hydrogen peroxide is oxidized by a stronger oxidant, free oxygen is produced.
