Elementary Productions: Liquid Oxygen

[Roomeoo222]

that is so fucking cool i can't believe, wondered if there was solid O2, and there it was. thx for sharing

[MucusFelidae]

Apollo1 mission combusted three astronauts in pure oxygen atmosphere of the cabin. Those american NASA engineers were stupid assholes. Remember, space travel was developed by Germans firsthand, when the Americans took over, they produced lethal fireworks.

[DaBeast842]

that cigarette is on stereroids

[nicktohzyu]

btw doesnt have to be manganese dioxide, both KI and yeast would work as well

[nicktohzyu]

FINALLY someone uses h202 instead of vanadium(V)

[dmx952]

i dropped chemistry :)

[pyro4869]

i didn't know you could drink air !?!!?

[greatwhitenorth112]

theres to many smart ass's on youtube 

[pratt123]

So if a cigarette burns that fast with extra oxygen, imagine how fast fires burned 300 mya when the percentage of atmospheric oxygen was roughly double at 40%. (This allowed dragonflies as large as a large dog and primitive crocs as large as great white sharks to exist.)

[nucleochemist]

Nice video. A better way of making this setup is to use a closed system. It seems that you just had the pipe sitting in the bottom of the test tube and the gas flowing past it. You can hook the flask containing the H2O2/MnO2 to a t-piece or y-piece adapter and connect a balloon to one end. Then attatch more tubing from the t/y-piece to the LN2 submerged test tube with a rubber stopper in the top. This way the sealed system wont lose O2, and the balloon will prevent too high pressure by expanding

[MrCantThinkOfAName]

Okay so today, i started out with nuclear fallout consequences, then to nuclear bomb videos, then to kittens, back to bombs, then to liquid nitrogen, and now this. odd.

[TheLiberalSoup]

why didn't nitrous oxide form?

[mewrox99]

@TheLiberalSoup

The reaction of nitrogen and oxygen require a lot of activation energy as it involves breaking the N to N triple bond. So oxides of nitrogen do not form at STP

[TheLiberalSoup]

@mewrox99

cool, thanks

[GroupWizard]

@TheLiberalSoup Becuse you have to react the oxygen and the nitrogen together and here you are not reacting them you are just useing the nitrogen as a coolent

[amun8isis]

thanks for your help... have gr8 day,... amunra....

[bagman4175]

When I was in the Air Force, we serviced the C-130s with Liquid Oxygen (LOX). They told us about “The Man from LOX” who had a cigarette shortly after servicing LOX. You were not allowed to smoke for at least a half hour after servicing because the oxygen would evaporate and get into your clothing. Apparently this person didn’t obey this rule, and yes, the guy did die.

[camtheman3x6]

what were to happen if you drank the oxygen ? despite your stomach freezing ?

[bluefox216]

this is cool but how do you get liquid nitrogen?

[ZenonDorinPower]

haha there should be another tutorial and so on

[purplemutantas]

@bluefox216 The easiest way to get liquid nitrogen is to buy it.

[vitorix24]

@bluefox216 Find some company that sells liquid gases. like N,O,He

[jpthecreaton]

tee hee...smokers beware

[wattapassa]

hahah you were being called at the beginning of the video xD

how much is the O3 contamination if you use this process? how much chlorine would i need to remove it?

[prodigious08]

What is the cost of production per 1 liter of liquid oxygen please?

[Grundalizer]

@prodigious08 Google that shit, wtf do you want a liter of liquid O2 for anyway

[prodigious08]

i was thinking to mix liquid oxygen and petrol to the engine car.

[Grundalizer]

@prodigious08 That's a bad idea, you'd be making a bomb inside your gas tank

[prodigious08]

@Grundalizer no nooooo to mix inside the fuel tank. both mus have separated tanks and the fuel with liquid oxygen will be mixed near the place when it goes to the piston. understand me?

[pps234]

i dont understand why nurses and doctors or scientist smoke when THEY are the ones who should know not to

[K1dKrusade]

why does anyone smoke?

[twirlywirly555]

Its cool liquid oxygen is attracted by magnestic fields too

[MrColoradan]

I believe you are mistaken about the reason LOX is blue. It is not because of the ozone, oxygen itself has some absorption lines in the red, which gives a blue color. Try your experiment with pure oxygen - I predict its liquid will still be blue. Try another experiment: let it distil away to nothing. Liquid ozone has a much higher boiling point than oxygen, and would concentrate as time goes on (the color would darken) if you were correct.

[mabakken]

Pure liquid Oxygen will always contain some Ozone, as it trimerizes. Also, liquid Oxygen does darken upon evaporation, due to the reasons provided by yourself :)

[lollol336]

Hey would breathing in the oxygen from the balloon be bad or is it fine?

[frapmail1]

Is it?

[lollol336]

I don't know nobody has answered me. An answer would be nice.

[mabakken]

Breathing Oxygen from the balloon would be fine, but extended exposure to high concentrations of Oxygen could have detrimental effects.

This can cause Oxygen toxicity in the body.

[frapmail1]

Answer

[vmelkon]

@mabakken I don't think that any ozone would form at that cold temperature. Also, there is concensus that LOX is light blue and liquid and solid ozone is dark violet. I have never seen liquid or solid ozone but I once read that it is dark violet in some chem dictionary.

[rocketplumber]

@mabakken Oxygen does not spontaneously "trimerize"; O3 has a positive heat of formation and will not form without major energy input. Also, it is not a simple grouping of three smaller units, it requires splitting an O2 molecule into atomic oxygen, which then reacts with another O2. Liquid oxygen contains no O3, not even parts per trillion.

I work with LOX routinely, and have let samples boil off many times. It does not darken.

[brunzmeflugen]

now i cant wait for high scool chemistry classes

[xXAlphaXx]

Haha, its not quite this much fun. I wish my Chemistry teacher let us play with liquid nitrogen D:

[oobermate]

I also heard the light blue hue of liquid oxygen is caused due to the fact that liquid oxygen has unpaired electrons.

[Alin19862007]

can oxygen gas be obtained by using concentrated H2O2? or is it necessary to dilute it?

[xpsychoticvanx]

You can use 30% H2O2 but the rxn occurs so violently that it is very hard to collect the gas. It is easier and more controlled to use diluted.

[Alin19862007]

thanks

[jdmhondapower0831]

what's the use of liquid oxygen?

what would happen if you were to drink it? lol

[magnum9987]

liquid oxygen is used as part of rocket fuel, where it is combined with liquid hydrogen and ignited. actually, the only byproduct is water. Liquid oxygen is also being considered for use in fuel cell cars. If you drank liquid oxygen, it would freeze your mouth and the upper part of your throat very quickly, so that your swallowing muscles would be impeded. The Oxygen would then turn back into a gas. Their would be minimal damage to you, unless it where housed directly down into your throat.

[RicardoGarciaPino]

the freezing of the cells in the troath forms minuscule cristals of water that when they heat to normal body temperature again, they make the cells blast, causing frostbite - like a burn.

[starshock01]

omg i need to try this with gunpowder

[Grundalizer]

You just have liquid nitrogen laying around?

[sciencoking]

the cigarette burns like magnesium o.O

[maglight117]

imgane smoking it

[magnum9987]

it would be better than regular smoking. The video indicated an extreme reduction in smoke, as the oxygen burned more of the mass, as thats all that smoke is: unburned material.

[Monxer]

isn't pure oxygen really flamable?

[chao129]

No, but if it finds something on fire, it makes it burn a lot faster.

[boomjustlikethat]

Actually, its about as flammable as flammable gets!

[chao129]

its just an oxidizer, if you had a tank of pure oxygen, it wouldn't light unless there was something in it for the oxygen to react with

[boomjustlikethat]

agreed. I was assuming fire was already present

I had a run in with O2l recently, which is why i've been checking out these videos

[KingHaines5]

oh reallly? learn something about chemistry before you say something stupid like: oxygen isnt flamable! cas its fucking explosive!

[mabakken]

Oxygen is NOT flammable! It is an oxidizing gas, and will therefore NOT burn by itself!

[RicardoGarciaPino]

i was wondering that if there was a method to polymerizate oxigen (something like (O-O-O-O-O-O...) it would be liquid oxigen at room temperature and it could burn by itself... well, not acutally burn, but would be extremely unstable and decompose to oxygen and ozone in an explosion.

[dragonridley]

I don't think it would hold together long enough to produce any noteworthy quantity.

I'm no expert though.

[TheMrlongisland]

@mabakken holy crap don't you realize that all forms of flame energy need oxygen and haveing a pure form of oxygen means that it is able to feed large quantites to to any flame and will expand it in a massive way

[thedude77777]

at 1:37 u say that there is a minute concentration of Ozone.. isnt it dark blue???

anywya nniice video !!!

please make some liquid ozone

(yes i knowits explosive) :P

[MysticVulture]

Ozone is light blue. And you're right. It is explosive. Just be careful.

[mankyman6]

dang, this brings a whole new marketing idea!!!!!

Oxygen in a can!

Or: OxyPop catchy eh?

[MysticVulture]

Not only can you make liquid oxygen yourself, but you can also order it from any gas station.

[Proph3tTroyer]

where do you get some of these nice toys eh?

[leetface2]

haha it's not very easy to get a lot of the things this guy has... my guess is a relation to his profession. you can't just go to home depot and buy the things in his videos. well maybe some of the things. tehe

[Proph3tTroyer]

I know, that's why I asked... hehehe

Chemistry is my calling, I'm planning on a career involving it... ATM though, it's just a hobby in my bedroom. The most interesting thing I've done is make elemental bromine.

[kelvincyh]

wanna get some and play with it XD!

[MysticVulture]

If you got liquid oxygen and lit it, I'd laugh if you got incinerated. My point is, if you had liquid oxygen, it would be very stupid of you to take a lighter and ignite it.

[mabakken]

Liquid Oxygen by itself is not flammable! You need something combustible to burn something.

Therefore, you can't light Liquid Oxygen on fire.

[thejava1]

I can't wait for college science to try and play with some LN2, it seems so useful in making other things as well.

Does the blue propery of liquid oxygen also represent why our sky is blue or perhaps deep water?

[MysticVulture]

The blue color of liquid oxygen is due to the minute amount of ozone in it. This also explains why the sky is blue.

[mabakken]

This does not explain why the skye is blue.

The skye is blue because of a physical phenomenon called "Rayleigh- scattering".

The principles of it belongs to physics, not chemistry.

[MysticVulture]

You should have also shown the paramagnetic properties of liquid oxygen.

[mabakken]

Yes I know :P

But you can observe it in my video "The Meissner effect" =)

[gamenern]

um.....isn't oxygen used to keep a fire burning?

[mabakken]

Yes, but you need something that can actually burn. Oxygen only "supports" the combustion.

[MysticVulture]

Yes. It is. You need a source, fuel, and air. Remove any one of these, and the fire will not continue.

[MysticVulture]

In an oxygen-rich environment, a fire actually burns hotter and starts faster. This is because oxygen is one of three things that keep a fire going. Remove any of them, and a fire will not continue. This is what CO2 does. It displaces oxygen in a fire, extinguishing it.

[cyanide444]

Anyone know a reliable source where I can get the chemicals? Most other sources sell for a huge amount of money.

[mrdan4]

i get myn from lindchem ltd

[cyanide444]

do they ship to US?

[mrdan4]

i dont know you have to email them about it

but as you live in u.s you should try united nuclear that sells just about all chems

[b43e65f77]

A harmless smoking way,haha

[b43e65f77]

Does something doped into liquid oxygen could self ignited?

[bla287]

I don't think so. You must know, a temperature increment of 10 Kelvin leads to double until even quadruple reaction speed. Boiling point of O2 is -183 °C, so it's ca. 200K colder than room temperature, thus the reaction speed is lowered to a millionth until a billionth, this cannot be offset by the higher density of liquid O2 compared to gas state (density ca. 1000 times higher).

But maybe it still would react with caesium :D

[cobrasniper555]

Please disregard my previous post. I wasn't thinking. I'd rather change the question to: Is there anything that can substitute the N2(l)?

[mabakken]

hehe...OK then :P

All you need is a substance that can provide a low- enough temperature for the Oxygen to condense. Search the Internet, and thou shalt find! :)

On a different note: if you mean to ask if there are other "easily available" substances to make the Oxygen condense: I don't think so. Dry Ice, for instance, wouldn't work. Neither will a very endothermic reaction.

[cobrasniper555]

Is there an easier way of condensing N2 than extremely modifying pressures and temperatures? Or will I have to face purchasing it from a chemical supplier?

[mabakken]

To put it simple:

Question 1: No

Question 2: Yes

=)

[cobrasniper555]

I love your videos mabakken! Would a cryo-tank (CO2) work as a substitute for the liquid N2?

[pyronaft]

canvas bags where filled with cumbustible materials like lampblack and sawdust then doped

into liquid oxigen,put in to borehools and ignited with a fuse. it detonated.

[tijgerjorri]

ScienceGeek, Jor here , from sc-madness

Can you tell me how you store your Liquid Nitrogen?

[mabakken]

Hi Jor. I store it in a Dewar flask! Quantities that are to be used soon I keep in a simple steel- thermos.

[Basco36]

cool video, doesnt oxygen react to magnets, why is that?

[mabakken]

Yes, Oxygen does react with magnets. This is a phenomenon called "paramagnetism". When liquid Oxygen is brought close to a magnet, it itself forms a magnet. This is due to the unpaired electrons of the triplet form (di- oxygen) of oxygen.

This is a grave simplification of the paramagnetism of Oxygen, but you get the point =)

[davidkoster]

Very doog video; really interstring;you have got very lot's of chemicals.
