Is the mixing of store-grade hydrogen peroxide 3% and glycerol in the ratio of 1:2 (V/V) at room temperature affecting the decomposition rate of hydrogen peroxide?


If you want to ruin both reagents, then you can go ahead and mix them. Hydrogen peroxide oxidizes glycerol to various reagents. A possible reaction pathway can be depicted as follows (Ref.1):

Oxidation of Glycerol

This reaction is catalyzed by transition metals and other substances (Ref.1-3).

    $\begingroup$ Hmm, interesting, I would not think oxidation stops at formic and oxalic acid. $\endgroup$ – Poutnik Jun 11 at 7:47
  • $\begingroup$ @Poutnik: I was surprized too. But this is s peer-reviewed papar so put my trust on the work. :-) $\endgroup$ – Mathew Mahindaratne Jun 11 at 14:20
