Capturing O2 to breath
So they have oxygen bars where you can go and breath pure oxygen because it makes you feel euphoric and probably is good for you because of added
oxygen to your blood.
So, I read a lab with pictures on how you would could get oxygen from hydrogen peroxide by adding magnesium dioxide as a catalyst to speed up the
decomposition of H2O2.
My question is, if you did this in a flask and captured the gas in a balloon would it be safe to inhale or would it have H2O2 vapor in it or something
else you shouldn't breath?
Or is it technically pure but just a bad idea to try?? Haha
Thanks!

Watch youtube video from NurdRage "Make MnSO4 from MnO2".
Where he says:
"MANGANESE sulfate is not MAGNESIUM sulfate".
MANGANESE DIOXIDE?

KMnO4, yeast and many other things also work. I think that it most likely by fit to breath since (pharmacy) H2O2 is fit to be used as mouthwash.

@bismuthate:
Yeast can make Hydrogen or Carbon Dioxide gases, but never Oxygen.

Yes, sorry. It was Manganese dioxide.

I would be using 27.5% H2O2, would this make a difference?

Well it depends how pure it is.(it probably is ok, but it's nice to be on the safe side)

Yes, in speed. It would make much Oxygen for short amount of time. You can control that rate of production (speed) by diluting it.

The peroxidase enzymes in yeast catalyse the decomposition of the peroxide, as does blood.

Other than for strictly medical purposes, inhaling purish oxygen is just another New Age fad from which probably little is to be gained. A
fairly expensive habit could develop from it.
Go for some invigorating walks in the hills or on the beach: more enjoyable and cheaper too. Probably more effective too.

Personally, I prefer oceanside jogs or swimming - but to each his own.
While it's true that more oxygen in the blood will mean better physical performance, it's not nearly a catch-all solution - especially considering
that after breathing pure oxygen, you'll be gasping down regular air like you're still in the mountains.

Well I say it's worth a try for the heck of it.
If you wanted to as deltaH said blood works to (alchemy time)

Yes, decomposition of hydrogen peroxide this concentrated can be powerfully exothermic and downright violent. Here is a classic chem demonstration
using 30% H2O2 and manganese dioxide.

I suggest much more dilute solutions of hydrogen peroxide.

I simply assumed blood contains peroxidase as dilute peroxide solutions used for disinfection fizzes
instantly upon hitting a wound.
I wonder if spit also contains some peroxidase? Would be good if the enzyme is dilute so the decomposition is not so fast. Anyone ever spit into H2O2
solutions?

I would think so because I have been told that it bubbles in the mouth.

Yes, very true. However, I just enjoy performing the chemistry in my home lab; having a [somewhat] practical use just makes it a little more
satisfying. Whether that be a cool crystal to keep or some H2 gas to ignite! In this case I think it would be cool to capture the
O2 gas from a reaction and breathe it (assuming it is safe) and briefly feel the effects that you would at an oxygen bar or hospital, etc.
Using the O2 to speed up something burning would be kinda interesting too.
If you can't tell I'm a pretty amateur "chemist" and I'm sure my interests will evolve with time, as will my skills and knowledge (I hope).

Imagine how easily it is to melt almost everything by burning charcoal in pure oxygen. About 3000 deg. Celsius or even much more.

Don't be concerned about mists or vapors... If you want to be extra safe, you could pass the oxygen through cotton wool.
Fear is what you get when caution wasn't enough.

Ok back to more serious matters, decomposing peroxide to oxygen will inevitably contain small amounts of H2O2 in the gas vis-a-vie H2O2's vapour
pressure, ergo, trace peroxide will make it to your alveoli and I'm guessing peroxide doesn't belong in lungs... hence I would advise against
inhaling said vapours!

Very good point, I was just reading about vapor pressure haha. Would the cotton wool idea prevent this issue??
Thanks!

Cotton wool would only prevent entrainment. That is when micro-droplets get carried in the fast
flowing gas stream. It will not, however, remove peroxide from the vapour. Only a catalyst can decompose the peroxide in the vapour.

The cotton wool might, but I would recommend passing the gas through a 'plug' of cotton wool or cloth impregnated/coated with manganese dioxide.
Except then you have the chance of inhaling manganese... Not fun.
