Why is H2O2 named hydrogen peroxide? - Chemistry Stack …
2016年6月11日 · 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.
redox - Half equations for H2O2 for its reducing and oxidising …
2014年5月1日 · 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)
decomposition - Why and how does hydrogen peroxide …
2019年5月27日 · $$\ce{O2^.- + H2O2 2HO^∙ + OH- + O2}$$ 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!
Hydrogen peroxide and potassium iodide reactions
2021年3月13日 · What is the explanation for the two possible reactions of $\\ce{H2O2}$ with $\\ce{KI}$ in acid media (iodide-catalyzed decomposition of hydrogen peroxide or iodide oxidation by hydrogen peroxide) and...
Reaction of hydrogen peroxide with sodium carbonate
2020年5月25日 · But I found that the $\mathrm{p}K_\mathrm{a}$ value of $\ce{H2CO3}$ is less than the one for $\ce{H2O2},$ which means $\ce{H2CO3}$ is more acidic than $\ce{H2O2}.$ As $\ce{H2CO3}$ is getting formed as the product (and then decomposing to give $\ce{CO2}$ ), shouldn't the reverse reaction be more favourable due to greater acidity of $\ce{H2CO3 ...
inorganic chemistry - What is the n factor of H2O2 undergoing ...
2021年2月26日 · 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.
Does H2O2 break down into H2O - Chemistry Stack Exchange
2015年9月4日 · $\ce{H2O2}$ -> $\ce{H2O +1/2O2}$ 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 …
organic chemistry - Estimating conc. of hydrogen peroxide at …
2020年3月30日 · I bought 20 liters of hydrogen peroxide ($\ce{H2O2}$) about two years ago and I was told that it was pure at that time. I'm aware of the instability of $\ce{H2O2}$, which easily decomposes into water and hydrogen. The $\ce{H2O2}$ at my premises had probably been decomposed partially within this period. According to its current practical ...
What exactly happened when I added KOH to hydrogen peroxide?
2014年5月5日 · There is some kind of reaction between the $\ce{KOH}$ and $\ce{H2O2}$. The $\ce{KOH}$ released a lot of energy when dissociating into the aqueous solution and then boiled the water, maybe reaching the temperature of 150.2 °C in which it also triggered the decomposition of $\ce{H2O2}$ into water and oxygen gas. On Wikipedia I read:
physical chemistry - Disproportionation of hydrogen peroxide ...
2015年12月25日 · However, if you just keep H2O2 by itself, without any oxygen, it will still decompose. This isn't captured by your proposed pair of half-equations, which essentially says that you need oxygen gas for the total reaction (i.e. sum of …
