Hydrochloric Acid (Part I) - Periodic Table of Videos

[KristoffDoe]

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

[aatishhake]

@periodicvideos :Can you make a Video of GRIGNARD's Reagent ??? i heard of it many time . Even in My Chem book

[Poponfu1]

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

[pampi14]

AAAAAAAAAAAAAARRRRGH, THE BIIIG FLAAAASSSK !!!!!!

[Pavle245]

Hey, why don't you make a video with fluoroantimonic acid or some other superacid? Greetings from Serbia.

[daviddanielgraham]

@5:06 "So... We're going to see what happens to a tasty McDonalds cheese burger after three and a half hours." Glad to see you were using your down time well prior to this experiment.

[jeboralatuyo]

you know what word i hate... the word tummy

[pug6666]

Make a video about Carborane acid.

[idman3333]

SCREAM like a girl yup shes bad at biology!!

[wl6309]

I love science.

[FrozenHaxor2]

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

[Oscarvalz]

You guys should make a super strong Soap for your lab Coats...

[jessecax]

6:34 Ebay !!!!

[boiledhooker]

This experiment should have been on "Super Size Me"

[AntiProtonBoy]

@XxDuhPedoBarrxX oh i know, i know... i'm just being an arse... :P

[Catboy379]

5 people have sodium hydroxide in their tummy

[migkillertwo]

I WANTED THAT CHEESEBURGER!

[gamesbok]

All vertibrates flush their food with hydrochloric acid.

[luigi90900]

why is ohm's law on a chemistry white board at 6:24?

[luigi90900]

To point to your tummy you need to be 5 cm higher.

[kefsound]

After dissolving the stuff from mc donald the hydrochloric acid became slightly more toxic.

[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.

[xXchocolate1997Xx]

@kefsound i dipped a penny in hot sauce from taco bell and it burned away the corrosion.

[pikachuthesquirtle]

NOOOOOOOOOOOOOOOOOOOO!!!!!!!!!­!! Why did u waste such a tasty burger?!

[XxD1EAN0TH3RD4YxX]

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

[AntiProtonBoy]

SHE USED THE ACID WRONG

[thexsoar]

Tommy was a chemist but now he is no more, what he thought was H20 was H2SO4 HEY! *cue applause* (wrong acid I know but I had to get that out of my head!)

[MORE4SP]

@thexsoar dude H2SO4 is sulfuric acid not hydrochloric acid.

[blueduderanch]

a well known auction site, do you mean eBay?

[jayjjj3]

A goose skull is nothing. My biology teacher had the penis bones of various animals.

[montey1017]

@jayjjj3 the only living creature with a bone in its penis is a racoon.

[jayjjj3]

@montey1017 No, search for a baculum on google.

[bluebell101]

i dare u to eat it lol

[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?

[vmelkon]

I heard that stomic acid is 0.5% HCl.

[Rededededu]

six eyes hahaha

[brandonGCHACHU]

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

[LizzyAston]

youtube autoplay has ruined my life

[melnadiacillian]

not me ...i vomited 3 times this norning

[Stormrunner0002]

A sad story.

In Canada, not too long ago, a woman moved out from her boyfriends house. He was cleaning the basement one day and found a metal 5 gallon pail with her three children melted in it.

[Naddig74]

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

[bullets0000]

Aqua Regia, check.

Hydrochloric acid, in 2 parts, check.

Up next: nitric acid?

[bustincapz]

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

[vvs2199]

@bustincapz It also helps digest bones and is necessary to transform pepsinogen into pepsin, a digestive protease.

[bustincapz]

@vvs2199 i did say it helps with somethings, and i didnt know what it was, so thanks for the info, and lol pepsin sounds like pepsi

[AlohaBay]

Dipping the Cheese burger in HCl, thats hilarious.

[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?

[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.

I think this is why lead is dangerous. Lead metal ISN"T dangerous, as the body can't abosorb it when coming in contact with it, but you eat it and it presumably turns into lead oxide, which can be absorbed by the body.

[1RadicalOne]

"I can guarantee that everyone has a sample of HCl with them."

Not me. ;)

I have KOH instead. It is so much better at breaking apart cells. ;)

[ParkourJayy]

Will you be doing a video on HF?

[rjhrjh3]

I wonder what would happen if you swallowed some zinc powder. Would that produce Hydrogen?

NOT TO BE DONE AT HOME!

[super1commenter]

@rjhrjh3 Good question! You'll burb hydrogen gas!

[M1XR]

hah its great to see chemists of this caliber failing to get the pop they want, experiments fail for me often haha

[j822bosh]

Well, the skull is mostly calcium phosphate so it will leave little residue. The cheeseburger was NAUSEATING as can be. Holy denatured protein batman! The only thing that makes HCl safer than sulfuric, nitric, and HF is it slow attack on meat and the thin film of fats and oils on our skin. If you have dry skin WATCH OUT!

[shantoydyson]

RUBBISH CLASSIC

[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.

[01793pop]

I thought you had to blow out splint and then it's suppose to relight it.

[aphtj]

she's hot

[sadbutterfly808]

can you tell us about HF and how it dissolves the bones??? :P

[Medic1911]

@sadbutterfly808 It will disolve calcium and other elements the bone is composed of.

[fakeplasticmeat]

Awesome video. I'm extremely pleased to see women so prominently featured in your videos. Science is fun, and you don't need a Y chromosome to do it!

[hyunchoi98]

how about HYDROFLOURIC ACID?

[klklzumzum]

they already made a video :)

[BeAnBeAn22]

what gives shit the brown colour

[tommatdan]

@BeAnBeAn22 bilibubin (probably spelt wrong ) it is made from the iron produced by the break down of old red blood cells in the liver that is then passed in to the intestines in the form of bile then excreted making your feces look brown (lovelly)

[MichaelKingsfordGray]

I bet Debs get sick of people calling her cute.

[sorry8140]

i got an ad 4 a "go-green" company called siemens hutchins. at what point did they think it was ok to call their company semen?

[88metallica88]

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

[MysteryDrifter69]

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

[andyroo24601]

That's going to change her "we recommend" profile in a severe way... "Customers who purchased goose skulls also purchased..." :P

[periodicvideos]

@andyroo24601 ha ha... nice one!

[NinjaAttack98]

@periodicvideos is it safe to work with hydrochloric acid at home because i have to do it for my science project....Please reply soon

[Pavle245]

@NinjaAttack98 What do you want to try?

[juanarruti]

@andyroo24601 also purchased what?

[LNOL]

Eh, you were a little low for your stomach.

[cherlax]

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

[Snake0987]

@cherlax  they did

[theburninator88]

@cherlax they already have lol

[joninlethbridge]

@cherlax they did. Check the link in the vid or on the PeriodicVIdeos website.

[periodicvideos]

@cherlax A link to our aqua regia pops up as an annotation in this video when The Professor discusses it!

[Travisdjtg]

ohh

[britmetal]

ahh eBay. No.1 for goose skulls :L

[CxC2007]

she's Cute.

[ScientiaPerceptum]

We, Biologists, are not going comment on the "tummy" as much as pointing out that it is called a Stomach.

Otherwise, great video as always.

Thank you.

[cheard1]

tilt your tube of hydrogen so it can mix with the oxygen in the air! then you'll get a nice "squeaky pop"

[norxcontacts]

HCL, aka Pool Acid, aka Muratic acid. This can be found at most hardware stores as a brick cleaner. Somewhere around 25% to 40% HCL.

[undulated]

very exciting and I'm very excited for part II

[chris536343]

At 2:56. Doesn't he mean boil at higher temperatures?

On the basis of increasing van der Waals forces, you would expect boiling point to become higher going down the group, but because of the hydrogen bonding present in HF, it actually has a higher boiling point than HCl.

[angryflan]

@chris536343 that's what he explained yes. You can do a funny trick with this Hydrogen bonding btw. Get a pvc tube, rub it with a cloth or paper and hold it close next to the water comming from a tap. The charged pvc tube will interact with the bonding ability of H2O molecule.

[chris536343]

@angryflan He said lower temperatures, but I think he meant higher temperatures. Otherwise it doesn't make sense.

[Fermions83]

@chris536343

your right, it should be higher temperatures. the h-bonding force is considerably higher than the van der waals force. a higher imf means higher boiling point

[shintsu01]

When will part II be available XD

[periodicvideos]

@shintsu01 I will be posting Part II this week.

[confiscator]

The anticipation is killing me!

[GodJasperX]

Like the colour of the lab coat. Used.

[culwin]

I would really like to know if I can eat a goose skull.

[dxd7122]

aww man, I hate cliffhangers.

[dbc616]

Well, muriatic acid is a certain dilution of hydrochloric acid, that is meant for cleaning stone

[theguycalledchris]

This stuff isn't at all like the mega-diluted varieties we use in chemistry and biology lessons, it's wonderful!

[callousg]

damn cliffhanger!

[varunasingh]

Debbie looks like Robot Chicken! :>

[varunasingh]

@varunasingh sorry I meant Chicken Little! :>

[whitsoxdude]

NOOOOO! I wanted to see the goose skull!

[chemiealex]

Cool!

I'm looking forward to part 2!

And I really like Debbie's face at 6:09 :D

[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

[paintballingfanatic]

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

[digdugdiggy]

awesome. goose skull melting is brutal

[Grundalizer]

I don't want to eat McDonald's anymore

[NiceyNiceGuyMike]

Somehow these videos get better and better.

[RoNM214]

Hydrogen should be collected under water....

method in the vid makes me laugh, i mean wtf!?

[sicarius1992]

2:50 "Usually molecules that are heavier boil at lower temperatures" Why is this true? Is it due to that a higher mass results in stronger VDW's? :/

[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

[sicarius1992]

@Doogeedoo12 This is kinda confusing me since everywhere I've checked it says larger numbers of electrons result in stronger van der Waals. I understand why hydrogen bonding is the reason for HF having a higher boiling than HCl point but I'm getting conflicting reasons for how the mass effects the boiling point.

P.S Sorry for the "Is it due to that a higher mass results in stronger VDW's? :/", that made no sense when put with my question :P

[sicarius1992]

@sicarius1992 Ok, I think I'm agreeing with what fnumb says, I don't know what to think really now xD Thanks for the kind reply though :)

[sicarius1992]

Apologies for the double post I accidently sent the reply to myself and not to Doogeedoo12 the first time around.

[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.

[fnumb]

@sicarius1992 I think he misspoke. he said it's surprising that HCl has a lower boiling point than HF, but that wouldn't be surprising if heavier molecules boil at lower temperatures. heavier molecules definitely follow a trend of higher boiling points.

[sicarius1992]

@fnumb Yeah that's what I thought too, I just didn't want to sound dumb in case he was correct.

[woodchuck1022]

dirty lab coat!!!

[TheStoicAgnostic]

I got this old book with little cartoon kids

looks like it's from the 50's

chemistry experiments or something

it says in relation to an HCl experiment

taste the acid. it should taste sour

it says nothing about its concentration, lol

crazy

[SupremeTestrun]

@thelleht yeah i'm looking forward to seeing it too

[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

[clarkcolt45]

so, if i eat zink... and light a cig, i will explode`? lol

[JaksProductions]

omg they turned cheezburger into sh%t lol

[antiswattt3]

cheeseburger part nearly made me cry :C

[narutostarfire]

NOOOOOOOOOOOOOOOOO i hate the word continue the show was getting in the good part i hate media LOL

but this is awesome i realize i saw every single periodic video keep them coming if not i will unsubscribe just kidding but its awesome LOL

[SuperSiddall123]

If anyone has ever seen Fringe the TV show does anyone think the professor with the large hair (don't know his name) looks like Walter Bishop (the mad scientist).

[valdisxp1]

I think the acid IMPROVED Mcdonalds food.

[TaylorL214]

@valdisxp1 so true

[Envergure]

What exactly makes chemicals "fume"?

[wilsonlaulau]

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

[Envergure]

@wilsonlaulau

+1, that would be entertaining!

[PartVIII]

i love these molecule videos

[wyzarme]

Magnesium Oxide is an Alkali? I thought Alkalis were defined by Hydroxide (OH-) Ions and Magnesium Oxide doesn't have one! Feel free to enlighten me if I am wrong!

[Peterditaa]

@wyzarme it is called an alkaline because it hydrolyzes (maybe spelled wrong, im no native speaker). It reacts with the water to form hydroxides. The effect is not really strong in the case of MgO but when you would use NaO2 it would get very very alkaline. So: you are right: Solid and clean MgO is not alkaline, water gives it polarity.

[petercourt]

@wyzarme I believe I'm right in saying MgO is a base, not an alkali (but do correct my if I'm wrong perodic videos!) An alkali is a soluble base. And a base is something which is a proton (hydrogen ion) acceptor. If you react MgO with water you get:

MgO + H2O --> Mg(OH)2

As you can see, the MgO has accepted hydrogen, and is hence a base. I am not sure, but I do not think MgO is soluble.

[omegacds]

Ahhhhhhhhhhhhhhh! I was really into that. Bring on episode two!

[Robberbaron15]

I have done the Zinc and HCl with 6M HCl and zinc metal chunks instead of zinc powder. Then use water displacement to capture the H2 gas.

[paulruddick]

Where's part two?????????

[ThatKidKnows]

@paulruddick Brady Hasn't Uploaded it Yet!

[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...

[TeoTheAwesome]

@Infloresence Haha! In Italy it's called "acido muriatico" too!

[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

[Medracin]

Lol, "And it did nothing." The story of my life in Chemistry lessons. Every single time I ever did an experiment, it would go wrong. I think that in the space of 4 years, I only conducted 5 successful experiments :P

[archaedemos]

Jaws Quote!! nice. lol

[AdmiralBud]

Oooh I get my HCl from Fisher too

[xKevTiffx]

Interesting.
