Why is H2O2 named hydrogen peroxide? - Chemistry Stack …
Jun 10, 2016 · The structure of $\ce{H2O2}$ is $\ce{H-O-O-H}$, and an $\ce{- O-O -}$ functional group is called a peroxide, by definition. The peroxide functional group is attached to a hydrogen atom, so it's called hydrogen peroxide.
Does H2O2 break down into H2O - Chemistry Stack Exchange
Sep 4, 2015 · $\ce{H2O2}$ -> $\ce{H2O +1/2O2}$ This might make it easier to understand. $\ce{H2O2}$ will homolytically cleave for form two $\ce{.OH}$ radicals. Radicals are very reactive and will start a chain reaction, but ultimately you will …
redox - Half equations for H2O2 for its reducing and oxidising …
May 1, 2014 · Is 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. These are my first attempts: $\ce{H2O2 + 2e^- -> 2OH^-}$ (in alkaline conditions) $\ce{H2O2 + 2H^+ + 2e^- -> 2H2O}$ (in acidic conditions)
Adding H2O2 in water does what to the pH of the water?
Aug 13, 2021 · My previous understanding was that $\ce{H2O2}$ spontaneously dissociates into $\ce{H2O + O2}$, including in water. I had imagined this would have no effect on the $\mathrm{pH}$ of the water its added to. The link above says if the water is acidic, $\ce{H2O2}$ will dissociate into hydronium + hydroperoxide ($\ce{H3O+ + HOO-}$). I imagine the ...
How does KI catalyze the reaction with H2O2?
Feb 14, 2023 · Since H2O2 decomposition happens incredibly slowly, the latter seems very unlikely. On the other hand, I can't seem to visualize why an anion would abstract the uncharged oxygen either. Yes, O has a lone pair, but that should give it a slight negative dipole moment and make it even harder to abstract, in my mind.
inorganic chemistry - What is the n factor of H2O2 undergoing ...
Feb 26, 2021 · implying that n-factor of $\ce{H2O2}$ is 2 but I am calculating n-factor of $\ce{H2O2}$ as 1 because the definition of n-factor is "the no of electron gained or lost per mole". As we can see 2 electrons are participating in this reaction so electron exchanged per mole is 1 which is equal to n-factor.
decomposition - Why and how does hydrogen peroxide …
May 27, 2019 · $$\ce{O2^.- + H2O2 2HO^∙ + OH- + O2}$$ And as $\ce{H^+ + OH^- = H2O}$, the net product formation is not altered. However, alkaline $\ce{H2O2}$ is well known to be less stable than acidic hydrogen peroxide (Ref.3) even in absence of light exposure, which accelerates its decomposition (which can involve radical pathways) liberating oxygen!
catalysis - What is the "mechanism" of the decomposition of …
Feb 3, 2020 · H2O2 may loose one O atom produce H2O, and the free O join another one coming from the next same situation in the next H2O2 molecule. Another mechanism would be to suppose that one H2O2 looses 2 H to produce O2, and then the two H are reacting with the the next H2O2 to produce two H2O. You may imagine a third mechanism. $\endgroup$ –
experimental chemistry - Why does the rate equation between …
Jun 8, 2018 · The ionic equation of the reaction between hydrogen peroxide and iodide ions can be written as $\ce{H2O2 +2I- + 2H+ -> 2H2O +I2}$ which is the rate-determining step as well. From what I have learnt, the order of reaction with respect to each reactant in the rate equation should be the coefficients of the respective reactants in the rate ...
What is the rate equation of decomposition of H2O2 with catalysts?
Dec 24, 2019 · I would expect similar results with H2O2 for other transition metal oxides, but MnO2 is claimed to avoid a radical based path (per Wikipedia), and the decomposition reaction can be energetic (and possibly explosive with 30% H2O2 in a closed vessel). Here is another example at "Active sites and mechanisms for H2O2 decomposition over Pd catalysts ...
