The peroxide functional group is attached to a hydrogen atom, so it's called hydrogen peroxide.周五, 03 4月 2026 21:15:00 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 ...周日, 05 4月 2026 17:59:00 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.周六, 04 4月 2026 05:58:00 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?周四, 02 4月 2026 09:42:00 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.周三, 01 4月 2026 05:04:00 GMThttps://chemistry.stackexchange.com/questions/125517/what-is-the-rate-equation-of-decomposition-of-h2o2-with-catalystsThe decomposition of H2O2 is complex and has been the source of several studies. On iron oxide surface, here is a cited work `Catalytic Decomposition of Hydrogen Peroxide on Iron Oxide: Kinetics, Mechanism, and Implications’. Some selected quotes: "As depicted in Figure 2, the decomposition rate of H2O2 appears to be independent of the goethite particle size. On the other hand, the ...周二, 31 3月 2026 14:52:00 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!周三, 01 4月 2026 19:23:00 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.周四, 02 4月 2026 10:03:00 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 ...周四, 02 4月 2026 05:03:00 GMThttps://chemistry.stackexchange.com/questions/179929/potassium-permanganate-and-hydrogen-peroxide-decompositionThe permanganate is a catalyst in the reaction. I am wondering if this decomposition occurs because the initial $\ce {H2O2}$ decomposition reacts with the $\ce {KMnO4}$ and reproduces $\ce {H2O2}$ which then again decomposes? How is the permanganate a catalyst?周五, 27 3月 2026 19:50:00 GMT
