  • redox - Half equations for H2O2 for its reducing and oxidising nature . . .
    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
  • Does H2O2 break down into H2O - Chemistry Stack Exchange
    $\ce {H2O2}$ 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?
  • acid base - When does hydrogen peroxide act as a reducing and when as . . .
    In 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
  • decomposition - Why and how does hydrogen peroxide decompose in the . . .
    Like 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
  • inorganic chemistry - What is the n factor of H2O2 undergoing . . .
    $$\ce {H2O2 + 2H+ + 2e → 2H2O}$$ 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!
  • How does KI catalyze the reaction with H2O2? - Chemistry Stack Exchange
    The 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
  • Mechanism for reductive and oxidative ozonide workup
    So, 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
  • Hydrogen peroxide and potassium iodide reactions
    2 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 what determines the prevalence of one over the other?
  • What is the rate equation of decomposition of H2O2 with catalysts?
    The 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’
