HELLO once again I am here to cause strife,

Potassium permanganate and H2O2 don't react.

BUT add ethanol and set it on fire

Then add the potassium permanganate....


BANG

hehehe

 




Care to explain?

[Borek]

Potassium permanganate and H2O2 don't react.

Yes they do.

2MnO₄^- + 5H₂O₂ + 6H⁺ -> 2Mn²⁺ + 5O₂ + 8H₂O

This reaction is basis of permanganometric titration for determination of the H₂O₂-content.

Want to put a K in there?

[Borek]

This is so called net ionic reaction. K⁺ doesn't change throughout the reaction, so it is called a 'spectator' and is removed from the equation.

[irishnenglish]

ok


well i still don't think they do react


we were told in class while the experiment was being done infront of us

[enahs]

So then they did an experiment and nothing happened? Nothing at all.

Seems like a stupid experiment to me.

They react.

That's right nothing happened until Flaming ethanol was added
