Chemical Reactions: Hydrochloric Acid + Aluminium Foil Bomb

[bertulforc1]

hydrogen chloride corrodes almost everything in your room, very bad for your lungs, eyes, throat, etc. you are young and more experience needed.

[bazzi54321]

That was aweasome

[jakoplant1]

What a stupid teacher...practically no safety precautions

[mattshark100]

You know its funny all those people think this is some hydrogen explosive risk. Hydrogen is flammable in atmosphere at about 4% (explodes at 18%). In this reaction there would be about 6 grams hydrogen produced. This is about 70 litres of gas. The room is more than 10000 litres of gas total meaning it'd be less than 0.7% hydrogen by volume, ie no real fire risk. The white smoke is water vapour and hcl vapour, NOT hydrogen, hydrogen doesn't have a colour or an odour.

[mattshark100]

The hydrogen gas however is harmless and far less dangerous (and less 'flammable') than filling your tank of gas at the gas station. Hydrogen is oderless and colourless, they were breathing vapour of HCL. At low concs like this it causes discomfort, its not dangerous like filling up your car or getting pepper sprayed at a protest rally. Hydrogen gas goes up and disperses, it is a very low fire risk.

[jonwal1010]

@mattshark100 Wow you're stupid. Hydrogen is much more flammable than gasoline and the smoke is pure hydrogen which can instantly cause lung burns and suffocate you. If you think it's harmless then please go try it and take a deep breathe so you die and can't spread you're stupidity anymore.

[mattshark100]

@jonwal1010 Actually i'm a chemistry grad like this guy and know more about it than a dumb fuck like you. Hydrogen gas is flammable, but this is a tiny amount of it which disperses very quickly with virtually no risk. You are far to stupid to comment on actual practical chemistry so do us all a favour and fuck off. Incidentally the real danger could only be the acidic vapour from the unreacted acid, hydrogen is oderless and colourless, ie not a white smoke. So once again don't be stupid.

[jonwal1010]

@mattshark100 The ONLY thing released into the air was hydrogen and if there would have been a spark in a room flooded with hydrogen it would have combusted unlike gasoline which is liquid and would simply fall on the floor. He even says at the end of the video what was released into the air. If you don't think that white smoke is hydrogen then please demonstrate with a live stream video!

[mattshark100]

@jonwal1010 You haven't got the faintest idea what you are talking about do you? The molar ratio of foil to gas in the reaction is 2 to 3 and the mass ratio is 26 to 1 meaning that the amount of foil he used would not have been enough to cause any significant risk. As for the 'gas' i submit the teacher made an error in his identification of what was choking them, hydrogen would be a painless silent killer whereas hcl fumes are acrid and painful. The 'white' gas is vapourised liquid.

[mattshark100]

@jonwal1010 To add to my previous response, my point remains, the acid causes discomfort, the hydrogen produced is the same energy output as 18g of gasoline and hence is low risk, if you can't understand this stop now before you continue making a chemistry fool of yourself. To reemphasise, if you think 6 g hydrogen is really dangerous, then perhaps the world is too dangerous for you.

[jonwal1010]

@mattshark100 So how do you know there is 6 grams of hydrogen produced? They didn't measure the amount hydrogen chloride used. Hydrogen is acid so if it's in the air they would be breathing it. For the last time the only way you can prove your point is if you do it so please make your own video of you mixing HCl+Al and breathing in that white smoke to show us all how safe it is.

[mattshark100]

@jonwal1010 I estimated it based on about 50g of al foil which produces 6g hydrogen and would be the limiting factor in this reaction. The estimate is probably high but even if it wasn't then you'd need at least 350g of foil to produce a low flame risk in that room. The white smoke isn't 'safe' it's got aerosol hcl, which i have breathed accidentally before and it can hurt a bit, so i wouldn't reproduce it, but it wouldn't kill them or harm them significantly unless they do it repetitively.

[mattshark100]

@jonwal1010 I already said the hcl vapour is a risk, the hydrogen is not, the hydrogen chloride is. Hydrogen is not acid in gas form, hydrogen and water is acid, hydrogen chloride dissocaiated in aerosol is acid and hydrogen chloride in pure form is a gas but not flammable, in a liquid form it is no more than 37% concentrated approx. So to recap. No flame risk, some very minor burning risk, YOU don't know anything about chem and i don't need a video to prove it, i have maths (and no video camera

[jonwal1010]

@mattshark100 Lol you're so stupid I don't even need to argue with you anymore. Everything you said is ridiculous anybody that can use google will see all the bullshit you said is false.

[mattshark100]

@jonwal1010 fuck off loser

[mattshark100]

@jonwal1010 cont. plus the actual 6g hydrogen produced in this reaction is equivalent in combustion output to 18g of gasoline. You put many gallons into your car everyday without considering the risk, the truth is this experiment is a flame risk hundreds of times lower than filling up your car at the garage, so know what it is you are talking about before you call someone stupid.

[ash4730]

@mattshark100 you just got OWNED!

[mattshark100]

@ash4730 ?

[woodyboyone]

cool.

[pudding0727]

u know that ur computer is gonna explode too ???? too fken close -.-

[neilsoda]

you are lucky your not blind or dead, you must have accidently done this before and killed a few brain cellsin the process which is why you have done it again indoors??? you complete tool.

[joshman94]

hydrogen gas is not poisonous, the only danger would be if it replaced all the oxygen in the lungs and you passed out, thus why he left. hydrochloric acid without gloves isn't that bad, it really depends on what molar concentration you have. Stop being faggots, this a cool experiment.

[BayouBluesMan]

u sir are an idiot

[thedisbatcher]

is hydrogen gas poisonous to breathe?

[Graypigs29]

Yo, any one got a lite?...

Other guy: Oh fuck noooo!....

[matthewcrissall]

wow, you were fucking breathing in all that gas. you fucking idiot

[BananaNinjaaVideos]

@matthewcrissall its hydrogen gas....

[wbttk]

You rode the line but you did make science cool.

[veryslyfox]

Only a dumbass would do this INDOORS. Next time, maybe one of you should be smoking while doing this experiment.

[Pinups2Showboats]

Acid residue probably ruined everything in the room!

[Pinups2Showboats]

You're an idiot! the acid residue probably ruined everything in the room!

[Pinups2Showboats]

ur an idiot!

[Pinups2Showboats]

ur an idiot!

[Pinups2Showboats]

ur an idiot!

[Hemorapker]

flakjacket pro...

[rallyramone]

Works also with NaOH, almost better. NaOH is much safer and cheaper.

[citers0504]

@ligerwarex Scientific equations like a boss!

[Ali3nat0r]

I was SO hoping you'd breathe the hydrogen in and start talking with a high voice. That would just about kill me with laughter.

[JonnyTommyGuns]

How do you like to breathe in that hydrogen chloride gas? It's pure poison. I hope you do the world a favour next time and die.

[taz069]

somebody light a match... LOL what a bunch of IDIOTS!!! Can't believe you did this in a close classroom.

[firestormpcs]

that is NOT HYDROGEN GAS THAT IS HYDROGEN CLORIDE GAS its aroslized in the explosion. you are an idiot!

[ligerwarex]

@firestormpcs Do your math. 2 Al + 6 HCl → 2 AlCl3 + 3 H2

[Bengycat]

i sooo need to do this

[SizzleMcFly]

dude, anyone bad-a** knows that it is'nt dangerous if you are careful, dog.

[BellaTheOwl]

and putting your life at risk?

[pompeyjim12]

Wish my teachers did that.

[TheGamersMedia]

this just makes me want to go out of my way to make a bomb and terror pepole out of my street

[DustinAndDillan]

@TheGamersMedia that makes no sense

[jakeiserman]

ur really a teacher?????? any educated science teacher would realize how stupid it is, to nonchalantly pour hydrochloric acid out of a container with no gloves on?!! and plus how extremely dangerous it is to have hydrogen gas floating around you.

[year9scienceteacher]

the purpose was to engage otherwise apathetics teenagers. being dangerous makes it more fun, thus more engaging, thus more likely to results in the desired learning outcome...therefore serving it's purpose. 

[DustinAndDillan]

@year9scienceteacher you should have used zinc pellets

[7410n0]

@year9scienceteacher There's a difference between danger and stupidity.

[ZIRBEEZZ15]

@year9scienceteacher because not wearing gloves is sooo dangerous and thrilling to a teenager

[banananutpie7]

Sniffing it hurts like a mofo O.O we did this in science

[aCagedApe]

lol

[aR3DF0Xa]

DANGER CLOSE!

[somervillefire]

cool, but really fuckin stupid. HCl gas burns your lungs and skin while the H2 could go Hindenburg on ur ass if theres the right concentration with O2.

[Thedog0101]

@somervillefire ROFL

[mbudd121]

HCL in your lungs anyone?

[sdvfuihsdiovsfiog]

this guy is stupid

[2kool2thinkof1]

your a fuckin idiot mate..

maybe outside next time buddy? not next to a computer..

[glenm51]

@2kool2thinkof1 Really, what a DA.

Acid splashed over the whole room, not to mention the corrosive gas.

Some kid will get hurt or even blinded trying to duplicate this nonsense.

UNREAL

[Ludinho27]

too bad i got caught by cops by doing these bombs in my town ...

[cheezyweezz]

Damn that was a big ass explosion

[jrbachman]

There is a way to limit the amount of HCl gas produced in this reaction. If an excess of water is used, AlCl3 forms hexaaquaaluminium ions that stay in solution:

AlCl3(aq) + 6H2O(l) ⇌ [Al(H2O)6]3+(aq) + 3Cl-(aq)

[Al(H2O)6]3+(aq) + H2O(l) ⇌ [Al(OH)(H2O)5]2+(aq) + H3O+(aq)

Why? It has to do with the temperature of the solution - heat from the rxn raises the temperature (kinetic energy) enough for Cl- to join with H+ and form HCl gas.

So, use just enough HCl with excess H2O and voilà.

[jrbachman]

Hydrogen gas is colorless and odorless, so what you were seeing and smelling was NOT hydrogen. The reactions taking place are:

2Al(s) + 6HCl(aq) ⇌ 2AlCl3(aq) + 3H2(g)

Then aluminum chloride reacts violently with water (HCl is an aqueous solution) producing HCl gas:

AlCl3(aq) + 3H2O(l) ⇌ Al(OH)3(aq) + 3HCl(g)

Thus, the gas is a mixture of water vapor, HCl, and hydrogen and the remaining liquid is a solution of HCl, H2O, and some aluminum hydroxide and aluminum chloride compounds.

[andymanpham]

i lol'd at the voice crack after the bomb went off. :3

cool vid :D

[Pantlessness]

didn't that guy just splash hydrochloric all over his room... and fill the room with HCL...

[AsThePurpBurns]

thats hella funny

[Ali3nat0r]

How about if you put a big balloon (or a jonny might hold more) over the lid of the bottle to collect a load of hydrogen and then blow that up

[imaball]

no gloves no face mask =[

[Zoomtronic1]

i used to make large ones when i was kid. 2 liter bottle and aluminum antenna chunks , we used to call it acid bombs, or kisela bomba

[marcusarelius23]

i'd say don't try this at home but hell i'm gonna! lol

[calem26]

hmm yeah dont do that indoors it a bit dangerous,but wow that was kool!

[ppyporpeem]

whish asshole does that dick head ur goona die soon if u do that again dumbo

[ppyporpeem]

whish asshole does that dick head ur goona die soon if u do that again dumbo

[ppyporpeem]

whish asshole does that

[matshroom]

idiots!

[Tarodos]

Are You mad?

I hope you don`t do such dangerous things near yours students.

You can teach this making fire from H2 Without using an pressure bomb, also the air suspension have HCl.

[TR1PPER85]

hydrogen is flammable. dumbass

[KeithSilcock]

I don't understand why you would do that indoors... Thats not just hyrogen gas thats also HCl. you're lungs must have gone through hell while sitting inside that room. What about your computer? didnt you get HCl all over that too?

[k0ent]

wait.. isnt hydrogen gas flamable?

[andr3ystefan]

@k0ent yes it is :)

[lleaves]

Should have been done outside.

[lapomole]

FUCKING IDIOTS

[brzokiller]

lol i makde this at home with salt acid amd al 2l bottle.... buuum :D

[glenngalezz]

thats fucking funny great stuff man

[MacsCanfly]

idiots
