So wait, if my stomach has Hydrochloric Acid in it... and I take zinc supplements, I can light my burps?

[@erowidoz]

She needs a third set of really, REALLY big safety glasses. That would be awesome.

[@NiceyNiceGuyMike]

Somehow these videos get better and better.

[@partingofways]

What I learned: it I eat powdered metal and resist the urge to burp, with time, I can become a dragon and breathe hydrogen flame.

[@ParkourJayy]

Will you be doing a video on HF?

[@OOmdebah]

I love your lab coats. Mine look the same way. I am afraid to laundry them, they might dissolve. Keep up the great work. Prof. OOm ACS Chemist College Prof Texas USA

[@Nikolaii2571]

I used Zinc metal dust in the production of aqua-marine colored pyrotechnic stars.

[@johnhoffman4998]

what would happen if you ate aluminum, since aluminum reacts violently with hcl, producing hydrogen gas and aluminum chloride in your stomach? I once ate aluminum foil on accident and nothing happened. I felt fine, but it was quite a large piece

[@hklausen]

Great videos you make, thanks. Could you make a video about nitric acid? Personaly I'm mainly interested in which metals it can desolve.

[@Doogeedoo12]

@sicarius1992 If I'm not mistaken, this is because of a molecules electron density. As molecules get larger, their ability to pull electrons from other atoms decreases. This is what's called a lack of a dipole moment. The reason you have liquid and solids is because the molecules can hold onto each other through intermolecular forces (eg. hydrogen bonding). When molecules get large, they lose these intermolecular forces and can only grasp each other through electron vibrations, which is weak

[@oldcowbb]

the HCl in stomach is for provide an acidic environment for enzymes to work or it really play a role in digesting?

[@Callordin]

Professor, there is some confusion about the use of antacids, proton pump inhibitors and other HCl reducing drugs in tearing digestive disorders. The book Why Stomach Acid Is Good For You may be a good starting point, even though it is written for the layperson. There is a lot of discussion of the biology, chemistry and many references.

[@MikkellTheImmortal]

I recently purchased a bottle of muriatic acid from the local hardware store. It's label reads HCI 20 Be. It's label says it's for adjusting the ph of your pool, I however use it to etch knives.

[@Medic1911]

The small bottle didnt go off because the hydrogen produced replaced most of the air in the bottle so there was no oxygen present. You can actually fill a bottle with pure hydrogen and get a ring of fire around the opening of the bottle. As it burns the system will suck in normal air through the center of the ring, and once you have enough oxygen it will burst. Pretty cool demonstration.

[@tylerurban6380]

Wait what would happen if I ate a lot baking soda? Would I not be able to digest? Would the bacteria in my stomach eat the food less efficiently?

[@EarlofDestruction]

Is 28% hydrochloric acid concentrated?

[@undulated]

very exciting and I'm very excited for part II

[@confiscator]

The anticipation is killing me!

[@Luigi90900]

Yes they do.

[@ProvenKilla]

We used 'muriatic acid' in our pool to balance pH! I knew it was HCl, but wondered why it was called that. Finally!

[@valerianardelean9235]

Why don't they use a stopper to trap the hydrogen

[@moff3tt]

maybe it is just late and I am tired. At 2:35 he talks about hcl has a lower boiling point than hydrogen fluoride, and it is surprising because typically heavier molecules have lower boiling points. What I don't get is there is nothing surprising about that since hcl is heavier than hf... Please someone explain what I missed.

[@vmelkon]

i don't think chemists call it muriatic. it's the construction worker's word. Just like some people say pencil lead. Some people say neon sign. Some people call fluorescent tubes neons. My brother calls all metals "iron". Is it iron?

[@archaedemos]

Jaws Quote!! nice. lol

[@bustincapz]

it does help digest food a little but its main use in the body is to kill all bacteria

[@ProvenKilla]

Aqua Regia- one thing that dissolves gold. Fun fact if you didn't know.

[@cherlax]

Can you guys make a video about the AWESOME "Aqua Regia Acid?" ^ ^

[@wilsonlaulau]

can Periodic Table of Videosmake a video about HCl with K?

[@crubba]

a regular, well known auction site... i wonder what that could be called? lol has the prof cut his hair or is it older footage - his hair is huge in the previous video

[@Morhua1]

Don't you mean that heavier molecules usually boil at HIGHER temperatures?

[@commodork]

What is Ohm's law doing in the background?

[@markandrews1219]

You stated that boiling points lower as you go down a column in the periodic table yet the halogens increase their boiling points as you go down to the heavier elements. I thought that the general trend was the increase in the size of the electron cloud - increased boiling point? I realise there are always excepts to be found to trends.

[@LogSubmarine]

It tastes good.

[@MrBadguy1337]

My fav acid!

[@Arceushero]

A lot of medical research has shown that that figure may be inaccurate, as salt is not as unhealthy as once thought.

[@Sentinalh]

Tummy is the technical term

[@iwtrihsiic]

It's good as an example of the effects of preservatives. Also a good example of what you shouldn't eat.

[@hippiechickie18]

WRONG. I am a chair watching this video. I don't have a stomach, and thus, I do not have a sample of hydrochloric acid with me.

[@kc8hnz]

In your tummy? Reall? Thats the most scientific description you can give?

[@blueduderanch]

a well known auction site, do you mean eBay?

[@ENr369]

@andyroo24601 also purchased what?

[@paintballingfanatic]

i always thought this weird.. want to know if a room is full of hyrdogen gas? light a splint!

[@NoWitnessesNoRegrets]

Instead of looking for evidence, you just say it's unbelievable. Now that is a new twist on the scientific method.

[@digdugdiggy]

awesome. goose skull melting is brutal

[@NissimRA]

Then you need something to ignite the Hydrogen like a match??? Hydrogen produces a lot of heat so you could suffer from burns you know...

[@walkingreject86]

1:05 Random lighter on the table lol.

[@varunasingh]

@varunasingh sorry I meant Chicken Little! :>

[@TheMrSeagull]

It's sad to see such a visceral reaction to pointing out Argumentum ad populum in a scientific video.

[@Naddig74]

I'm a martyr to my personal sample of HCl...pass the Omeperazole

[@DaanSnqn]

The female person in the beginning should wash her lab coat lol

[@ColonelFrosting]

*Hides Vodka Bottle* No I'm not...

[@Nebulak187]

not human ones. but those of many mammals have

[@jessecax]

6:34 Ebay !!!!

[@s07561277]

Ironic that chemists don't like to change the name of things. This explains why many people say "aluminum" instead of "aluminium".

[@KristoffDoe]

Either she is very tiny person or those are the biggest safety glasses I have ever seen!

[@hackforloser]

tummy

[@AntiProtonBoy]

SHE USED THE ACID WRONG

[@FlyingPiper13]

I see...

[@LiaEA]

???

[@ColonelFrosting]

Mine does x)

[@cillianwilliamson16]

not me ...i vomited 3 times this norning

[@carpetmonk]

nothing better than a lady in a dirty lab coat.. raawrn..

[@JuanPretorius]

youtube autoplay has ruined my life

[@ProvenKilla]

Ya... maybe that was a slip of the tongue..?

[@frala5DK]

Its food :D

[@AnarchyRacing306]

I wonder what the person's IQ is that has the grey afro?

[@VeradoonKing]

wrong.

[@CxC2007]

she's Cute.

[@Shmifflepuff]

I can't believe it's even debatable that McDonald's is not good for you.

[@TomPark1986]

Maybe I should go to university to study chemistry. I love the lab stuff.

[@FrozenHaxor]

I'm looking forward to see a video about nitric acid! Awesome channel!

[@theedrstrangelove]

The Hydrochloric acid in Gastric Juices does not digest or otherwise break down food, it merely activates the digestive enzymes. You were using concentrated HCl. Our stomachs have a much less concentration than that.

[@2Spookeh4Me]

Put real bread, cheese and meat in next time, very different colour and results (yes it still dissolves)

[@cpovey1]

Current thinking by biologists is that HCL is in your stomach as much for food safety reasons than for dissolving and helping to digest food. Most bacteria that are eaten (and everything has bacteria on it) are destroyed by the acid. Note that the burger was not totally dissolved by the acid.

[@justaFL1P]

Thank you for the amazing and informative videos! I only wish the profs at my university did these kinds of things as well! :P

[@tbmavenger71]

Is alkaline the same thing as a base?

[@chemistryfu]

yes

[@4mathieuj]

Yes

[@uwotm8363]

I have to say the video is a bit misleading: The acid in the stomach is much more dilute and dissolving a McDonalds cheeseburger is both insinuating that they are synthetic and that it is a real example of what happens, however HCl in the stomach merely catalyzes enzymatic reactions.

[@MORE4SP]

@thexsoar dude H2SO4 is sulfuric acid not hydrochloric acid.

[@MGlBlaze]

...You managed to get a goose skull off (I'm guessing) E-bay? The things people sell... come to think of it; The things people BUY. xD

[@brandonGCHACHU]

@ 1:00 ....my god woman! Launder that labcoat!

[@Grundalizer]

@sicarius1992 hydrogen bonding >>> Van Der Waals forces when it comes to strength of the bond. Because Flourine is the MOST electronegative atom, it has a massive dipole in HF, and so the partial charge on a Hydrogen atom in HF hydrogen bonds with the partial negative charge on the Fluorine atom of another molecule of HF. On top of that, since HF is a much smaller molecule than HCl, more molecules can hydrogen bond with each other than could HCl molecules in the same volume.

[@MaBuSt]

When the male scientist first pored HCl into a glass container, it fumed a lot. When the camera moved away and they brought in the cheese burger, it looked like the glass container was on a random counter, and not in a hood. Did I see this incorrectly or should this have been done in a hood?

[@NissimRA]

err..no. That would not be possible because the body produces HCl in very little amounts. The digestive process in the stomach is usually done by Pepsin with some HCl. So you won't have an EPIC EXPLOSIVE BREATH

[@a.g.9847]

why in the acide muriatique picture did it say poison? I know it will kill you but not due to toxicity.

[@Infloresence]

Here in Portugal it is still sold as 'acido muriatico' usually on the bottom shelf so the kiddies can get their hands on it lol...

[@gouskin]

Yes. Humans and horses are the only animals (That I'm aware of, there are most likely more) that don't have bones in their penises.

[@Syrlantar]

Penile bones of animals. Also known as a 'baculum.' Humans don't have them, but many animals do.

[@XxD1EAN0TH3RD4YxX]

Do the factories that produce it use supermodels as their primary source of getting it? lol XD

[@TheScientist40]

Placing McDonalds burgers where they should be, leave it to the British to do that first.

[@mitchumsport]

in your tummy? on which side? you can tell she's into chemistry and not biology/anatomy

[@ThomyThompson]

What do you think Alkali means? Yeah, basic ionic salt....-_-

[@Jackcabbit]

Some animals actually do have bones in their penises. It's called a baculum.

[@ruadeil_zabelin]

Funny how it even says in dutch what it is on the bottle

[@Poponfu1]

umm.. someone buy her a new lab coat ! that one is disturbingly dirty lol

[@88metallica88]

The science library at Florida State University is named after Paul Dirac

[@spaceface124]

I don't think I will eat another McDonalds Cheesburger after this....

[@ProvenKilla]

Maybe he meant it was significantly higher than and not just higher.

[@j7ndominica051]

This acid is good for cleaning toilets.

[@wollywog]

Eh, you were a little low for your stomach.

[@kc8hnz]

God, science nerds are so hot!
