what happens if you put a peeled banana in hydrogen peroxide?

Question

how much foam will form?
how long will it take until something happens?

Answer 1

Lancenigo di Villorba (TV), Italy

A peeled banana's pulp results a very reactive matter againsts Hydrogen Peroxide.
In effects, mature banana's fruit (e.g. you decide on the basis of its smelling) contain several organic compounds able to undergoes Chemical Oxidations by means of Hydrogen Peroxide.
The most known among these organic ones are the banana's sugars, e.g. I think to fructose

HOCH2-[C4H6O4]-CH2OH(aq) + 4 H2O2(aq) --->
---> HOOC-[C4H6O4]-COOH(aq) + 6 H2O(aq)

so I could think Fructose becoming Fructaric Acid....there isn't Oxygen bubbles.
Why you wrote about Gas Bubbles?
Well, banana's pulp contains also Light Esters able to emit the characteristic smelling ; I doubt these one may react against Hydrogen Peroxide.
On the other hands, banana's pulp contain also residual Poly-Phenolic Compounds which are responsible for bitter taste in greenish exemplares.
These phenolic matters are related to particular banana's proteins known as PHENOL-OXIDASEs.
The latter ones result able to react against Hydrogen Peroxide joining in several Redox Equilibria : in a complicate multi-reaction fashion, Hydrogen Peroxide release Oxygen bubbles.

I hope this helps you.

Answer 2

H2O2 is a strong oxidizer. You should see the rapid oxidation (rotting) of the banana.

The calculation you ask is based on how much banana and how much peroxide you use.

Answer 3

You will have a banana with good breath.
