+rafael rubingh You can try it at home if you can sulfuric acid let alone that high of a concentration, although it would be pretty stupid to handle sulfuric acid if you have no prior chemical knowledge or how to handle certain chemicals. :p
thank you when you shot this video for using protective wear as far as showing people to always wear rubber gloves or chemical gloves and proper safety equipment
Vapor Trust me it smells like it too. One of my high school teachers thought it would be a good idea to do this in a classroom. We had to evacuate the room for about 20 minutes because it smelled so bad.
This was well presented. The reaction was part of the syllabus at O-level in the UK until the late 1960s and is described in the 'chemistry bible' of the period: New Certificate (or School Certificate) Chemistry by Holderness and Lambert. I hadn't seen the sugar cube version of the reaction before.
A few more safety suggestions: Don't do this if you aren't a trained chemist. If this is not enough to convince you, read my sulfuric acid safety manifesto which follows. You might want to run to the bathroom first as this could take a while. (Edited: Technically it's possible to do this safely and NOT be a trained chemist or a t least someone with significant lab experience, but in my experience amateurs tend to get sloppy or forget an important safety rule eventually.) A lab coat is good. A rubber apron is better. Lab coats reduce the amount of chemicals that get through to your skin by adding an extra layer of cloth that can be removed after exposure. Rubber aprons completely stop the acid. Do this under a fume hood or if you insist in doing it in your home, do it under an exhaust hood or outdoors. The fumes from the acid and from the reaction can irritate or even scar your lungs. Theoretically you could die, but unless you have a medical condition (like asthma or emphysema), get a really strong whiff right out of the bottle or you're doing this in a small, confined area like a closet, you PROBABLY won't die. Lung scarring is no joke though even if you live. You might also induce chemical pneumonia which is potentially fatal. Operate under the assumption that you WILL get some in your eyes or on your skin or soaked into your clothing. Can you get to some means of gently rinsing your eyes while blinded? Is there a shower or garden hose or a swimming pool or some other means of rapidly rinsing it from your skin/clothing? Again, can you get to this water source while unable to see? Be prepared to get naked fast if you get some on your clothes. Are you in a situation where getting naked fast would be too embarrassing or illegal? Don't do it then. If you get this stuff in your eyes, your eyelids will clamp shut from the pain. It is an uncontrollable reflex. YOU WILL BE UNABLE TO OPEN YOUR EYES WITHOUT PRYING THE LIDS OPEN WITH YOUR FINGERS! Every second counts when you get sulfuric acid in your eyes. A very, very short exposure might result in little or no vision loss. A few seconds more and you'll need a cornea transplant. A bit longer and there's no fixing it. As the video poster noted, safety goggles are a must! A full face shield is another viable option. A fume hood with the see-through shield lowered is a good additional precaution, but not a substitute for goggles/face shields. REGULAR SAFETY GLASSES ARE NOT GOOD ENOUGH!!! I don't care if your high school science teacher let you get away with regular safety glasses. They are NOT good enough. Although this experiment doesn't involve water, a few more safety tips involving acid and water follow: Sulfuric acid gets hot when it mixes with water, as in hot enough to boil. It can spatter easily when this happens so don't assume that all you have to do is pour very carefully and you'll be okay. Add Acid - A chemistry safety rule that means always add acid to water and not the other way around. This way if it suddenly boils, you're more likely to get splashed with hot slightly acidic water than with undiluted hot acid. Sulfuric acid is one of the acids which most readily dissolves human flesh, ESPECIALLY if it is hot and as previously mentioned mixing in water gets sulfuric acid really hot. This is most dangerous where losing a tiny amount of flesh is a really bad thing, like losing the surface layer of your eyeballs, face, genitalia, etc.
You really must be a scientist Sir It’s good that you explain to people all the bad things that can happen to you why anybody would mess around with sulphuric acid in the first place what far only crazy people mess with that shit and of course the scientist knows what to do with it most the time it’s locked up in the cupboard a good place for it through away the key very dangerous stuff
Yeah when handling concentrated sulfuric acid you should we're acid-proof gloves, which are a lot thicker. The ones used here would probably be disintegrated immediately and then stick to your skin, making things even worse in comparison to not wearing gloves at all. Also you'd usually fill the acid from the bottle into an empty beaker first.
In 1973 I went to downtown Chicago with a couple buddies. We brought a plastic wastecan, 10 pounds of sugar, sulphuric acid, and distilled water. We put the can in front of the Tribune building just after we put the sugar and acid in the can. The trick to getting a reaction as I was told was that you had to toss a glass or so of distllled water in after mixing the other 2. The water would react violently with the pure acid, and kick off the attack on the H22 O11 part of the sugar molecule. That is molecular water, and it is the reason the thing works in the first place! Few compounds love water like concentrated sulphuric acid. Even in a molecular 2-to-1 ratio as part of other chemicals! Anyway, we drove off. I walked by the can and threw in the water a couple minutes later while my buddies waited down Michigan Ave. Sure enough, it caused bedlam! Fire department showed up, no one would go near the seething mass! The whole idea of the Trib was to get it in the paper, and it did!! The boiling mass of carbon was several times the size of the can, which of course melted from the heat of the reaction!! You should have seen the people around there when it started off!!
7:38 "Now we can tell that this is a exothermic reaction because we could see that a lot of energy was being released" Haha what... "You can tell that it's an aspen tree because of the way that it is."
OMG! You are BUCKY??????? I have watched your java and c++ tutorials ages ago and I was always wondering how you looked like. So this is you. You look way better than I imagined. I just wanna say THANKS MAN.
Your chemical formula is incorrect. the sulfur atoms don't just disappear. you do realize this produces toxic sulfur dioxide gas as well? o.o that's the stuff that smells rank, and it's a respiratory irritant too.
Do Not, do not put latex gloves when handling sulfuric acid! There are special chemical gloves for that. It's better to have a soda solution that you can dip your hands into in case of exposure.
Sulfuric acid doesn't destroy latex nor nitrile gloves, you don't need special gloves. Fuming nitric acid is that acid that will destroy latex or nitrile
On one hand your video title says "dont try this at home" and on the other hand you are encouraging people to perform such activity at home by giving instructions
@@tonyb8660 This is what happens when you don't pay attention and start judging people before thinking. He didn't post the entire chemical equation because it's much longer than what he posted. Instead, he clearly wrote "+ mixture water and acid (sulfur dioxide)" under the products 12C + 11H2O. The guy also has a disclaimer: Do not try this at home. Clearly this is for educational purposes only for folks who practice chemistry in an academic setting.
I keep trying to remember what was in the old volcano simulation in grade school before they made teachers use baking soda and vinegar. It was like potassium chlorate, sulfur, and phosphorus/carbon compounds. Just things that burn and make cool looking ash. But now teachers can only use soda and vinegar like a homeless guy puking beer foam.
Just for the sake of accuracy, "powdered sugar' also contains cornstarch to allow for easy pouring. If one tastes both granulated sugar and powdered sugar, they will be able to taste the difference. I would be interested to know why and how the corn starch changed the reaction.
TJ Williams That made me laugh xD could just picture some little american kid screaming down the stairs to his mum "MUM I CAN BURN THINGS I HAVE BAKING SODA!!"
+buckmister5263 That's why he say "the first thing you need...", "you can get this at amazon.com...", "you also need to...", "before you start you should..." hehe
Gets a tight capsule and puts a mixture of sugar in it. injects Sulfuric Acid into the container then shakes it up and throws it as far as they can to the other side of the cafeteria...i love how you can turn anything into a weapon of destruction or at least that is how i think of the world
+Bony Paul (סבסטיאן) Sulphur reacts so it forms SO2, which is the gas you can see coming out. It can be toxic and it also makes you cough quite hard, so you don't wanna mess with it xD
cameron smith You're right, there was not water at the beginning, however, there is at the end. Bucky explains it at the end of the video. Basically the sugar combined with the acid makes carbon and water. Thats how the water got there.
+TheEPROM9 The law of conservation of mass states that the mass of the reactants is equal to that of the products... So if the steam and other products were collected the mass would be equal :)
if something goes wrong and you need to use an emergency eye wash station, you wouldn't really be able to get your contacts out for a proper wash, which would do more damage and obviously make later treatment way harder. Obviously you wear goggles, but it's an extra precaution.
Because certain chemicals, even as vapor, can melt the lenses to your eye balls and Stevie Wonder the shit outta you. CS gas will do this. It's used in military gas chamber training and sometimes by riot cops in shitty countries. Inbred methamphetamine cooks have done that heating certain drain cleaners too quickly. I would be depopulating us too if I were the global ruling elite. Not with giant lasers like they've been using to level California, (CA wildfires true story) I would kill everyone with kindness. I would be the best illuminate. They should hire me. But yeah, no contacts in a lab and no jewelry or long hair in auto shop.
Clown Whisper ? She was with a black guy. I think you need to look up the definition between racist and racial. They're pretty subtle, but I have faith in you.
Little Johnny was walking down the street tossing a bottle in the air when he runs across a priest. The Priest asks Johnny "whatcha got, son?". Johnny says "this here is the most powerful liquid in the world, it's sulfuric acid". Priest says "son, this is the most powerful liquid, it's Holy Water" as he holds up a small bottle. Priest says " a drop of this on a woman's womb and she'll pass a baby". Little Johnny says " that's nothing, a drop of this on a cat's ass and it will pass a motorcycle". Haha!
In small quantities, sulfur dioxide irritates the nose, eyes, throat and lungs. Inhaling large quantities of the gas or longterm exposure leads to swelling of the lungs and difficulty breathing.
And the purpose / result of this is...? "This video is presented to you by Sulfuric Acid Manufacturing of America..." Oh, and just as an afterthought, you may wish to have adequate ventilation and a chemical breathing mask because, you know... your lungs.
I used to do this when I was a kid in grade school. You may wonder how a child managed to procure concentrated H2SO4. Never mind. I stopped it after a couple of times because the carbon produced is etched into the beaker and impossible to clean out. I remember seeing the same experiment on one of the kid's science programs on TV, like Mr. Wizard.
@G J seeing as shes had two black husbands and the urban legend is the black men have huge cocks i'm curious how his statement is considered "racist".....funny how you snow flakes can see racism in truth.... it's like me saying Asians are better at math than blacks and you screaming double racist statement! .....it's ok, if you stay inside the big bad truthful world cant get you....
