The peroxide functional group is attached to a hydrogen atom, so it's called hydrogen peroxide.Fri, 10 Apr 2026 20:45:00 GMThttps://chemistry.stackexchange.com/questions/10375/half-equations-for-h2o2-for-its-reducing-and-oxidising-nature-in-acidic-and-alkaIs there a complete list of all the half equations for $\ce {H2O2}$ - both oxidation and reduction, in acidic and alkaline conditions? I've looked on the internet but can't seem to find a list with all of them.Sat, 11 Apr 2026 04:38:00 GMThttps://chemistry.stackexchange.com/questions/66408/when-does-hydrogen-peroxide-act-as-a-reducing-and-when-as-an-oxidising-agentIn basic medium: $\ce {H2O2 + 2e- -> 2OH-}$ I was unable to find any pattern in all of the reactions I studied above (except for potassium ferrocyanide, for which the medium triggers the electron addition/removal) to recognize when hydrogen peroxide behaves as an oxidising agent and when it behaves as a reducing agent.Sun, 12 Apr 2026 03:25:00 GMThttps://chemistry.stackexchange.com/questions/146793/what-is-the-n-factor-of-h2o2-undergoing-disproportionation-reaction-liberating-o$$\ce {H2O2 + 2H+ + 2e → 2H2O}$$ Here 34.01 g of $\ce {H2O2}$ consumes two gram equivalents of hydrogen as an oxidizing agent. So the equivalent weight of this compound as an oxidizer in acidic medium is 34.01/2. The moral of the story is that normality is solely dependent on what reaction is being used!Sat, 11 Apr 2026 19:54:00 GMThttps://chemistry.stackexchange.com/questions/171365/how-does-ki-catalyze-the-reaction-with-h2o2The equations $ (1)$ and $ (21)$ shows that $\ce {H2O2}$ can undergo spontaneous self-oxidation-reduction, and is therefore, thermodynamically unstable. Accordingly, $\ce {H2O2}$ decomposes spontaneously and exothermically, but slowly to oxygen and water at room temperature.Tue, 07 Apr 2026 10:26:00 GMThttps://chemistry.stackexchange.com/questions/35869/does-h2o2-break-down-into-h2o-o-or-h2o-o2$\ce {H2O2}$ will homolytically cleave for form two $\ce {.OH}$ radicals. Radicals are very reactive and will start a chain reaction, but ultimately you will end up with water and oxygen products from $\ce {H2O2}$. (Why does it form two hydroxy radicals? because the O-O single bond is weak and unstable - see MO theory) How do we know this?Sun, 12 Apr 2026 10:42:00 GMThttps://chemistry.stackexchange.com/questions/184746/mechanism-for-reductive-and-oxidative-ozonide-workupSo, to summarise for the both the reductive and oxidative workups, the role of water is to perform hydrolysis on the ozonide and then either Zn or H2O2 is used for the oxidation/reduction.Mon, 13 Apr 2026 08:24:00 GMThttps://chemistry.stackexchange.com/questions/116006/why-and-how-does-hydrogen-peroxide-decompose-in-the-presence-of-lightLike all other peroxides, hydrogen peroxide ($\ce {H2O2}$) also consists of a relatively weaker $\ce {O-O}$ bond, which is susceptible for light or heat. In the presence of light (the UV light from the sun catalyzes the reaction), $\ce {H2O2}$ spontaneously decomposes into water and oxygen.Fri, 10 Apr 2026 10:37:00 GMThttps://chemistry.stackexchange.com/questions/7759/reaction-intermediates-of-mno2-catalyzed-h2o2-decomposition-reactionManganese dioxide catalyzes the decomposition of hydrogen peroxide to water and oxygen gas. But what are the intermediates in this catalyzed reaction?Sun, 12 Apr 2026 11:17:00 GMThttps://chemistry.stackexchange.com/questions/127385/what-is-the-mechanism-of-the-decomposition-of-hydrogen-peroxideBelow is one way to write it that shows what the enzyme does and avoids the uncertainty of the details: $$\ce {E + H2O2 -> E-O + H2O}\tag {1}$$ $$\ce {E-O + H2O2 -> E-O2 + H2O}\tag {2}$$ $$\ce {E-O2 -> E + O2}\tag {3}$$ In words, the enzyme binds to the first molecule of hydrogen peroxide, release one molecule of water and holds on to the other oxygen atom (via the iron bound to heme bound to ...Mon, 06 Apr 2026 03:25:00 GMT
