Hydrogen Peroxide and Blood

Watch how this stuff react together.
The reaction:
H2O2 turns into water and oxygen as a result of enzyme called 'catalase', which is inside the blood.
H2O2 solution concentration was 3%.

I just did this cuz I had a bad nosebleed. I bled into a little cup and added the hydrogen peroxide. It was cool. It foamed over the cup and got warm. Any science geeks know why it got really warm? I know it probably has to do with the chemical reaction occurring. But anyway, it was pretty cool.

@classicrockboy93 yes,it's an exothermic reaction(realeses energy). The reaction is quite simple(not balanced):

H2O2→O2+H2O  ∆H<0(Energy is realesed)

@hoochis Well, it's all over your body mate;)

@dandisc88 exactly!

@toastp13pm4tz What about oxygen, though, do you deny that exercise oxygenates the blood, or do you deny that oxygenating he blood is healthy? I see what you mean about oxidizing agents, but isn't it a balance? I mean runners look like hell because of all the breathing they do, but they are thin and healthy while they are alive. They age faster, but would you say that running is unhealthy because of too much oxygen?

@ella5024 That only proved that biologists suck at chemistry.

[ella5024]

@QuantumOverlord I did take chemistry. I have a B.S. in Biology, in fact. It shouldn't be harmful, because when you exercise, or do deep breathing, you are oxygenating your body too! Oxygen can be harmful, I know that, but it is also very necessary for life, and a benefit of exercise is oxygen in your body.

[QuantumOverlord]

@ella5024 You obviously did not take chemistry, Oxygen is an oxidising agent obviously, but the reason why Oxygen is harmless and Conc Hydrogen peroxide is a level 3 health hazard is because H2O2 is far more potent, to the extent where you can do serious internal damage, ask any chemistry professor from any top university. Or alternatively do what I do and study the subject yourself.

[ella5024]

@QuantumOverlord Exercise is an oxidizer, too, will that kill you? Better not breathe too deeply!

[ella5024]

I wonder how this reacts in the body. I've been using food grade H202 for a while. I drink a tiny sip of it in the morning. I can't wait to use it when I get up now, otherwise I feel like I'm swallowing all kinds of bad germs.

h202 is toxic to most organisms but luckily we have an enzyme called catalase that breaks h202 down into H and O that is what foams.

@ReneeRoulette Kills cells? H-peroxide is good to use on wounds/lacerations (works better on fresh one's)

Hydrogen peroxide gets rid of anaerobic bacteria in the wound due to the decomposition reaction of H2O2. Blood is simply the catalyst and when O2 is released from the reaction the bacteria is completely gone.

h-peroxide from drug stores and etc. are safe to use because it's only 3%. Now anything other tan that wouldn't be a good idea to put on a wound.

[ReneeRoulette]

Awesome. It should never, ever be used in a wound because it kills cells and prevents healing (soap and water, much) but it can be useful in the ears once a month and occasionally in the belly button. I can't believe this stuff is known to treat wounds! Ouch.
