This is a completly fake experiment, anyone can hold hidrochloric acid in such concentration on a hand, there is nothing new in that, it's very reactive against aluminium but not to much against organic compounds, anyway if you can hold it on your hand for over 5 min. i will believe you.. dumbass..
@Doncoxino Ha, I'd like to see you hold 37% hydrochloric acid in your hands. Obviously you don't know that 37% is the highest possible concentration. Big mouth, no knowledge. I tried this stuff, with 37%, and it works!
Yah I want to see him put on sulfuric acid and then he would not be so smug, in fact the part that the 98% acid touched would blacken as the sulfuric acid sucked the water out of it
@MTHKITEBOARDS Stomach acid is 0.5 percent HCL. it is mostly water, potassium chloride (KCl), and sodium chloride (NaCl). Do your research. Also, even 0.5% HCl causes irritation of the throat when you puke.
37% HCl is highly concentrated "fuming" Hydrochloric Acid. The maximum concentration (about 40% w/w) is limited by the solubilty of (gaseous) Hydrogenchloride into water. The HCl-concentration in the stomach fluid is about only 0,5 %!
Hydrochloric can cause burns but and should be handled carefull, but it will not normally cause burns inthe time shown. (just don't get it in your eyes). It is the least dangerous of the strong acids. Vaseline, mineral oil or any other oil will keep water based acids from touching the skin (oil and water don't mix) so there is nothing extraordinary about dermashield. Even normal skin oils provide some protection.
@Johnsavag HF is a WEAK acid!!!! the reason being the fluoride ion is is the smallest from the halogen series thus the covalent bone between H and F is very strong, which means low ionisation to H3O+ (hydroxonium ion) and F- (fluoride ion) in water
the strongest acid in the halogen series would be HI since the iodide ion is very large leading to large degrees of ionisation leading to large differences between Ka (dissociation constant) of HF and HI
@darrylportelli True, but it HF has the unique ability to quickly penetrate through tissue due to it's small molecular size, and the fact that is goes through the skin via non-ionic diffusion. In terms of damage to the human body, is worse. Read the MSDS on the two. Swallow some HF, you're not waking up. Fluoride poising is way worse then iodide poisoning.
so i can drink this thing and then drink acid, as it protects me from burning, i can pee the same acid i drank, so i can attack my enemies with acid coming from my dick, THANK YOU VERY MUCH!
You might ask oh where is the aluminium look at the foil it's aluminium
And we do not know wether this man cheated and switched pipette and filled it with another liquid
This being said 37% hydrochloric acid on the skin doesn't really do much damage within 15-20 seconds of spill on skin. Though it hurts like shit if you have a crack in your skin. (Speaking of experience)
I would like to see this gentleman attend same procedure using Red/White fuming nitric acid.
Im sorry my friend you are wrong. Copper is a noble metal and less reactive than hydrogen. The bubbles are a definite formation of gas... yes hydrogen gas. But it comes from the single redox replacement of Zinc (s) metal and HCl (aq) acid. Since 1982 the U.S. has been making pennies from 97.5% zinc metal and 2.5% copper metal plating. Zinc is more reactive than Hydrogen therefore it replaces it and releases it into its gaseous phase. Copper is a spectator and not involved in the reaction.
What about magic acids?( in chemistry, you don't learn about them too much, but magic acids have a ph level at around -50 to 70, which is extremely strong!)
pshawww... i accidently got hydrochloric acid on my finger once and it did absolutely nothing. I just washed it off. Next time use some lab grade high concentration hydrofluoric acid and see what is does. (science nerds know what I mean by this).
it's true that copper reacts with HCl with presence of oxygen, but it follows reaction
2Cu + O2 + 4HCl -> 2CuCl2 + 2H2O. This reaction is very slow. The man on this film is cheating, 'cos copper(II) compounds are blue, sometimes green(as chloride) and copper(I) compounds are insoluble.
The pH range has nothing to do with how horribly it will attack your hands.. HF is a an acid that will kill you and probably wouldnt protect you against that, even if you watered it down to a low concentration.
This product would seemingly be very effective for bartenders that have to constantly use citrus to make drinks, since it could prevent them from getting 'bar rot' i.e. Paronychia.
@noonan706, no, actually HCl won't react with Cu. HCl doesn't have enough oxidizing strength to it, and for the same reason H2SO4 won't react with Cu either. HNO3 will. If you want to dissolve Cu with HCl, add H2O2 to the solution.
What we saw in the video was the HCl reacting with Al, and cleaning off the coin.
@TheRolemodel1337 Well seeing as he started off with it's not to be used in place of protective equipment, don't think he'd be dumb enough to do that.
HCl doesn't get much more concentrated than 40% because the hydrogen chloride gas escapes the water. 37% is classified as concentrated HCl for that reason.
put a small amount sulfuric acid in the palm of your hand, then put hydrofluoric where you put the sulfuric acid, then slap yourself in the ass with that hand and drink 10 kilograms of cyanide while yelling "HAIL HITLER!" XD
Copper doesn't react with hydrochloric acid... only with nitric. Also try putting 98% sulphuric acid on your hands. I have tried it and it burned my hands quite badly even when I got to the tap in less than 3 seconds.
@mewrox99 the amount of H2SO4 is significantly less than the huge flow of water so there is negligible increase in temperature. anyways i didn't have any scars :P
Wow! Can this protect against Fluoroantimonic acid which is 20 quintillion times stronger than sulfuric acid!? 20 quintillion: 20,000,000,000,000,000,000
First, that reaction was with aluminium foil, which is highly reactive with regards acids. Secondly, you can clean a penny with lemon juice, or brown sauce, both of which are only irritant with sustained contact. A 36% solution of HCl (unless I've made a stupid mistake,) is pH of about 4.4, which is nothing like low enough a burn.
You've made a stupid mistake. A 36% solution of HCl has a pH of <1. It's definitely a very acidic solution, but not one that would do a lot of damage to ones hand IF washed off quickly.
Youtube is having a spaz out again. :P I have had hot, saturated KOH and 98% sulfuric on me. It does indeed tingle and start itching and burning. But I mean, it doesn't melt your skin off. Give it a good rinse and you're good. If I was handling them all day, commercially, I'd have some puncture resistance chemical gloves on to save myself the time being careful and having to wash my hands.
No, I've had boiling KOH on me as well. It does start to tingle fairly quick. But it's not like people expect, immediately boring a whole through you and melting your flesh off. [edit: deleted the last message, spelling mistake]. I usually don't bother wearing gloves, I'm just careful to not spill it on myself and rinse it off. If I was handling it all day, I'd have proper, THICK, gloves on so I didn't have to keep washing my hands
I am not trusting that with sulfuric or nitric. I am a chemist, i work with pretty much everything you can imagine... HCl does not really hurt when you get it on your skin, not if you wash it off in a minute or so. Nitric or Sulfuric, however, will immediately burn.
Not saying this isnt a good product, it might be, but it won't stop the harsher acids at all imo.
@ACiDxVoLTaGe sure, I would agree with that the additional dehydration/exothermic reaction of sulfuric acid will cause additional damage vs. other acids of similar strength. Sulfuric is a quite strong mineral acid in and of itself, however, and will definitely cause burns (corrosion if you like) even if water wasnt present.
got to say, I just visited your site, and the video on there isn't helpful at all. particularly if you're a chemist. and if you're dealing with something harmful that could splash on your face or skin, you need a cheap visor and proper gloves, not to rely on the idea of having fully covered your skin with the product.
I've had concentrated sulfuric on me before, and saturated KOH. So long as you rinse them off, it's not an issue. It is an issue when they get into those little cuts on your hands, then it stings like a mother. having left KOH on my skin for too long at one point, it got into a tiny cut and started eating away. when I got round to washing it, I had a small purple bruise under the skin for weeks. but I like the idea of gloves you can coat onto your hands; normal gloves get all sweated up
@lexichronicle2 I had had both on me before as well.. Sulfuric will immediately eat through the skin and cause the water it contacts to boil. Saturated KOH (and when I get it on me it is usually hot, almost 100C, will also burn immediately but it defats first and doesnt penetrate as well... but you will definitely get burned with it almost immediately.
I am thinking you arnt using concentrated acids or fully saturated KOH. /shrug.
@lexichronicle2 and honestly, if you have a problem with gloves "sweating up" get lined gloves. The liner will prevent the sweat slipping and it also prevents bacaterial from living in the gloves which can eat away at the skin. I personally use Ansell Sol-Knit Reinforced Nitrile Gloves most of the time, sometimes with disposable gloves underneath (depending on what i am working with). I only have to use Level A stuff sometimes.. now THAT is hot working!
lolololololololol THIS IS RETARDED. You people better know that HCl doesn't react with copper. It's eating the foil. They obviously know very little about Acids. i get 12% HCl on my hands allllll the time and i just leave it there. never been burned in my life by it. i use it about twice a week for things i cant tell you :P
I have spilled 6M HCl and 3M H2SO4 all over my hands before; for short periods of time, they pose little danger. Ergo, I question just how much effect this "DermaShield" had in this usage.
If you are so sure of the product, try with HNO3. THAT will do some serious damage to unprotected skin.
Hello i worked for years on a Electroplating Facility and please stop scamming people HCL 37% is not as bad i want you to try the same trick using Sulfuric Acid,Nitric acid or even caustic soda.I want the same guy do it with he same tranquility.
Hey to make it even less harmful try Hydrogen Peroxide yes the same you use for cuts,mouthwash and dye hairs but 80% why this chemical easy as you must know your hand will turn skin temporary white so no trick using water.
@TheAPTec Perchloric acid would be interesting. I used to work with Ammonium perchlorate when making rockets and I know firsthand that it is a powerful oxidizer. Many (-)electrons are involved here, but I don't really know if DermaShield would stand up to it, and if it does then for how long?
the only acid that can eat through copper is nitric acid, the hydrochloric acid is reacting with the aluminum if it was dissolving the penny, a large amount of poisonous gas would come out.
@matataka This may be true but considering a penny is only coated in copper; the item itself is actually zink, couldn't he have scratched it and the acid would then dissolve the zink, making it APPEAR to have dissolved copper? Or are my facts wrong on this one?
@cjmack1973 that is actually not true... the copper with HCl will under go a single replacement reaction:
2HCl + 2Cu --> 2CuCl + H2 (for Cu 1+)
2HCl + Cu --> CuCl2 + H2 (for Cu 2+)
and you would thus get freed hydrogen gas. that was what we saw in the video (the bubbles) Im sure this "DermaShield" is completely useless but still check your facts before stating false things.
@noonan706 This is only true for practical use. Theoretically HClaq doesn’t attack copper at all. That only occurs if oxigen is involved, which is always the case under ordinary conditions. Small amounts of oxigen that are soluted in water and in copper too if it’s less than pure, act as a catalysator.
@noonan706 Copper does NOT react with HCl. Trust me, I am an expert. Copper only reacts with acids that have oxigen in their molecular structure. It first oxidizes to CuO, and then the Copper(II) oxide reacts with the acid. HCl cannot oxidize copper to CuO.
@CarnalDiafragma When you add the HNO3 to help react Cu with HCl, the nitric acid oxidizes the Copper from 0 to +2 (meanwhile, the nitrogen in the nitric acid is reduced from +5 to +2, and the nitric acid decomposes into NO and water). The copper +2 reacts with HCl to form the CuCl2. You can use any other oxidizing substance.
@chimie96 Ah I see. Another advantage of CuCl2 being formed immediatly, is the equilibrium being drawn away from Cu(NO3)2, so more copper will dissolve. This is particuarly useful for when dissolving gold instead of copper.
@noonan706 this is not exactly true this reaction of HCL and Cu is an equilibrium which is benefit of the existance of copper, so there wil only be a tiny bit of CuCL formed
Copper won't dissolve into Hydrochlorid Acid due to it's noble character and positive electic potential. Only metals with a negative potential (eg. Zinc, Magnesium, Aluminium) will react with HCl and dissolve. Copper is a semi-noble metal (like Silver and Mercury) and needs an oxydizing acid like Nitric Acid to be dissolved.

You've made a stupid mistake. A 36% solution of HCl has a pH of <1. It's definitely a very acidic solution, but not one that would do a lot of damage to ones hand IF washed off quickly.

It's true.
The destroying power of acid onto your skin in decending order:
conc. H2SO4 >>> conc. HNO3 > conc. HCl

Youtube is having a spaz out again. :P I have had hot, saturated KOH and 98% sulfuric on me. It does indeed tingle and start itching and burning. But I mean, it doesn't melt your skin off. Give it a good rinse and you're good. If I was handling them all day, commercially, I'd have some puncture resistance chemical gloves on to save myself the time being careful and having to wash my hands.

No, I've had boiling KOH on me as well. It does start to tingle fairly quick. But it's not like people expect, immediately boring a whole through you and melting your flesh off. [edit: deleted the last message, spelling mistake]. I usually don't bother wearing gloves, I'm just careful to not spill it on myself and rinse it off. If I was handling it all day, I'd have proper, THICK, gloves on so I didn't have to keep washing my hands
lexichronicle2 1 year ago
I am not trusting that with sulfuric or nitric. I am a chemist, i work with pretty much everything you can imagine... HCl does not really hurt when you get it on your skin, not if you wash it off in a minute or so. Nitric or Sulfuric, however, will immediately burn.
Not saying this isnt a good product, it might be, but it won't stop the harsher acids at all imo.

@capierce Can I just say that acid doesn't burn it de-hydrates which causes corrosion.
ACiDxVoLTaGe 1 year ago
@ACiDxVoLTaGe sure, I would agree with that the additional dehydration/exothermic reaction of sulfuric acid will cause additional damage vs. other acids of similar strength. Sulfuric is a quite strong mineral acid in and of itself, however, and will definitely cause burns (corrosion if you like) even if water wasnt present.
capierce 1 year ago
got to say, I just visited your site, and the video on there isn't helpful at all. particularly if you're a chemist. and if you're dealing with something harmful that could splash on your face or skin, you need a cheap visor and proper gloves, not to rely on the idea of having fully covered your skin with the product.
lexichronicle2 1 year ago
I've had concentrated sulfuric on me before, and saturated KOH. So long as you rinse them off, it's not an issue. It is an issue when they get into those little cuts on your hands, then it stings like a mother. having left KOH on my skin for too long at one point, it got into a tiny cut and started eating away. when I got round to washing it, I had a small purple bruise under the skin for weeks. but I like the idea of gloves you can coat onto your hands; normal gloves get all sweated up
lexichronicle2 1 year ago
@lexichronicle2 I had had both on me before as well.. Sulfuric will immediately eat through the skin and cause the water it contacts to boil. Saturated KOH (and when I get it on me it is usually hot, almost 100C, will also burn immediately but it defats first and doesnt penetrate as well... but you will definitely get burned with it almost immediately.
I am thinking you arnt using concentrated acids or fully saturated KOH. /shrug.

@lexichronicle2 and honestly, if you have a problem with gloves "sweating up" get lined gloves. The liner will prevent the sweat slipping and it also prevents bacaterial from living in the gloves which can eat away at the skin. I personally use Ansell Sol-Knit Reinforced Nitrile Gloves most of the time, sometimes with disposable gloves underneath (depending on what i am working with). I only have to use Level A stuff sometimes.. now THAT is hot working!

lolololololololol THIS IS RETARDED. You people better know that HCl doesn't react with copper. It's eating the foil. They obviously know very little about Acids. i get 12% HCl on my hands allllll the time and i just leave it there. never been burned in my life by it. i use it about twice a week for things i cant tell you :P

I have spilled 6M HCl and 3M H2SO4 all over my hands before; for short periods of time, they pose little danger. Ergo, I question just how much effect this "DermaShield" had in this usage.
If you are so sure of the product, try with HNO3. THAT will do some serious damage to unprotected skin.

Hello i worked for years on a Electroplating Facility and please stop scamming people HCL 37% is not as bad i want you to try the same trick using Sulfuric Acid,Nitric acid or even caustic soda.I want the same guy do it with he same tranquility.
Hey to make it even less harmful try Hydrogen Peroxide yes the same you use for cuts,mouthwash and dye hairs but 80% why this chemical easy as you must know your hand will turn skin temporary white so no trick using water.

@TheAPTec Perchloric acid would be interesting. I used to work with Ammonium perchlorate when making rockets and I know firsthand that it is a powerful oxidizer. Many (-)electrons are involved here, but I don't really know if DermaShield would stand up to it, and if it does then for how long?
Nguli34689 1 year ago
the only acid that can eat through copper is nitric acid, the hydrochloric acid is reacting with the aluminum if it was dissolving the penny, a large amount of poisonous gas would come out.

@matataka True =)
Serostern 1 year ago
@matataka This may be true but considering a penny is only coated in copper; the item itself is actually zink, couldn't he have scratched it and the acid would then dissolve the zink, making it APPEAR to have dissolved copper? Or are my facts wrong on this one?

HCl won't react with Copper
cjmack1973 1 year ago 15
@cjmack1973 that is actually not true... the copper with HCl will under go a single replacement reaction:
2HCl + 2Cu --> 2CuCl + H2 (for Cu 1+)
2HCl + Cu --> CuCl2 + H2 (for Cu 2+)
and you would thus get freed hydrogen gas. that was what we saw in the video (the bubbles) Im sure this "DermaShield" is completely useless but still check your facts before stating false things.

@noonan706 HCl won't react with copper unless there is a strong oxidising agent like hydrogen peroxide
obeyyourmaster666 1 year ago
@noonan706 This is only true for practical use. Theoretically HClaq doesn’t attack copper at all. That only occurs if oxigen is involved, which is always the case under ordinary conditions. Small amounts of oxigen that are soluted in water and in copper too if it’s less than pure, act as a catalysator.
fpm1979 11 months ago
@noonan706 Copper does NOT react with HCl. Trust me, I am an expert. Copper only reacts with acids that have oxigen in their molecular structure. It first oxidizes to CuO, and then the Copper(II) oxide reacts with the acid. HCl cannot oxidize copper to CuO.
chimie96 10 months ago
@chimie96 Copper can react with HCl, but not by itself. A little added HNO3 should do the trick and it will form CuCl3[-] and CuCl4[2-] complexes.
I doubt it will go through a CuO intermediate like you say, and in the case of added HNO3 it will go through a reaction with nitrosylchloride.
CarnalDiafragma 9 months ago
@CarnalDiafragma When you add the HNO3 to help react Cu with HCl, the nitric acid oxidizes the Copper from 0 to +2 (meanwhile, the nitrogen in the nitric acid is reduced from +5 to +2, and the nitric acid decomposes into NO and water). The copper +2 reacts with HCl to form the CuCl2. You can use any other oxidizing substance.
chimie96 8 months ago
@chimie96 Ah I see. Another advantage of CuCl2 being formed immediatly, is the equilibrium being drawn away from Cu(NO3)2, so more copper will dissolve. This is particuarly useful for when dissolving gold instead of copper.

anonymous2431 9 months ago
@noonan706 this is not exactly true this reaction of HCL and Cu is an equilibrium which is benefit of the existance of copper, so there wil only be a tiny bit of CuCL formed

You are the worst chemist seen on YouTube
The copper will not react with the hydrochloric acid in a single displacement reaction
Because coppers oxidation potential is lower than that of hydrogen so it cannot displace hydrogen from hydrochloric acid.
However what you see is aluminium undergoing a single replacement reaction
2 Al + 6 HCl(aq) --> 2 AlCl3 + 3 H2
This is due to aluminium having a higher oxidation potential than hydrogen
Look up the reactivity series

Copper won't dissolve into Hydrochlorid Acid due to it's noble character and positive electic potential. Only metals with a negative potential (eg. Zinc, Magnesium, Aluminium) will react with HCl and dissolve. Copper is a semi-noble metal (like Silver and Mercury) and needs an oxydizing acid like Nitric Acid to be dissolved.
196Stefan2 4 months ago
Well HCl doesn't actually react with skin instantly as it does with metal. This has something to do with PH values i guess.
Still, give it some time by not washing your hands and let it soak, then see what happens.

You can't dissolve any more than 37% hydrochloric acid, after that it just starts fuming out gas.
It's nowhere near as strong as sulphuric acid, of course.
