What Is H2o2 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
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 and Click here point up 2 to get an answer to your question writing hand balance the following redox reactions by ion electron methodh2o2aqfe2aqrightarrow fe3aqh2ol in acidic solution

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 The empirical formula is the simplest whole number ratio that defines constituent atoms in a species Given the above definition the empirical formula of hydrogen peroxide is simply OH Note that the molecular formula is ALWAYS a multiple of the empirical formula That is EF n MF where EF MF are empirical and molecular formulae respectively and n is a

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 effectiveness I guess the concentration is still above 15 but I can not be sure The oxidation number of H is 1 The oxidation number of O is 1 You assign oxidation numbers to the elements in a compound by using the Rules for Oxidation Numbers The important rules for this problem are The oxidation number of H is 1 but it is 1 in when combined with less electronegative elements The oxidation number of O in compounds is
