Back in before we did acids and bases in chemistry everybody wanted to know what would happen if you combined an acid and a base. When our chemistry teacher finally caved in and showed us......... Huge disappointment
Pretty awesome video, clearly shows how dangerous both an acid and a base can be. I think that most people don't realize how dangerous a base can be. Keep up the great videos Brady!
My science teacher played this in class and I flipped out because I never thought he would play one of these videos but I was so darn happy when I heard Sam's voice as I looked up from my notes
@@AverageAlien theres a huge difference though. A oxidized metal acts as a weak base. It now has an oxygen to give off in reactions, and thats what it does. Al2O3 + 6HCl -> 2AlCl3 + 3H2O
In another video where a lightbulb was submerged in HF acid I noticed a similar effect. The surface of the liquid is where the activity seemed to be most prominent and cuts a neat line around the objects. Why is this? What's the property of a liquid that makes the surface so different? I imagine it's related to the actual energy being exerted in surface tension. I have done many electrolysis experiments where the anode will separate at the surface and remain.
+samramdebest It would burst, then everything would stop because the coke dilutes the base by a lot. What am I sayin'... truth is, it'd trigger a thermonuclear explosion that destroys lab. The product of reacting coke with NaOH would also be highly corrosive and would melt a hole through the basement.
OreWaSpencer regular coke has a pH of 2.5-3.5, with 2.5 cited for coke while you stomach has an pH of 1.0 hydrochloric acids pH value is based on how much it's dilluted, a solution with 32% has a pH of -1
rangedfighter Hence why I asked for the molarity of the solutions. I really like this channel's videos, but I'm disappointed that they don't go a little further and introduce some standard science into the videos. Explain to the masses the different scientific measurements of concentration, the calculation of pH, cite the values involved in the video, explain the mechanisms for how acids and bases interact with the aluminum in the can, etc. I want to learn and not be dazzled by a "magic" show.
I've done this (aluminum+solution of sodium hidroxide) once, when a boy, at my backyard, in order to produce Hydrogen gas. Water electrolisis was too slow. The first time, it produced so much H2, and so fastly, that the bottle i was using to collect it exploded near my face. That made me learn about reactions velocity and how to control it through concentrations of the reagents. Chemestry is awesome!
I would never have expected NaOH to do that. I used to dissolve cans with HCl (brick cleaner) as a kid and collect the hydrogen that evolved with a garbage sack and light it. This brought back memories.
Someone asked and there was no reply button so I thought I would copy and paste the question. How does sodium hydroxide react with aluminum? NaOH + Al --> NaAl + (OH)-? How does that work? Where does the hydroxide end up? My understanding is that OH is not a product. I think H2O is also in the reactants and Hydrogen gas is a product. In chemistry not all the information is given in a chemical formula. The real chemical equation is below. 2Al(s) + 2NaOH(aq) + 6H2O → 2Na+(aq) + 2[Al(OH)4]- + 3H2(g You see you have Aluminum, Sodium Hydroxide, and water = sodium, Aluminates. and hydrogen gas.
This isn't an experiment; it's a demonstration. The goal of the whole video was to show how acids and bases would react with an aluminum coke can. It had me pretty entertained. Just appreciate what they're showing you and don't be too pretentious.
I would definitly say that bases are much more scarier than acids. The fact that if you get an HCl solution in your eyes, it will be possible to save it if you clean it quickly. If you get a NaOH solution in your eyes, they are completly fucked.
From Wikipedia: "Two variants of the metal's name are in current use, aluminium and aluminum. The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990 but, three years later, recognized aluminum as an acceptable variant. Hence their periodic table includes both. IUPAC prefers the use of aluminium in its internal publications, although nearly as many IUPAC publications use the spelling aluminum."
The acidity of the coke in the can isn't enough to break through the internal plastic coating so it stays intact. Though give it long enough it will start to react with the coating. Also another reason that the Base reaction was more vigorous was that not only do it react the AL with the NaOH but also causes the AlO layer to react with the water in the NaOH solution.
RJ Lee Actually, no, the official name was originally aluminium, then it was changed to aluminum, then back to aluminium(that is of course the abridged version of the story, a bit more complicated than that)
One of the first proper chemistry experiments I did at my university was the production of KAl(SO4)2•12 H2O using soda cans. Since we were looking for a relatively pure sample we had to thoroughly remove the plastic coating and paint. Nothing like seeing something solid like an aluminum can melt away into a solution. the next lab we turned it into a precipitate that was as white as snow! :) I miss science...
The whole acid being dangerous and evil comes form the old lead acid batteries when the batteries were made of glass, so you had to be super careful with them not to break them and get acid every where.
@rubius0 Glass is silicon dioxide (mostly) and that reacts very little. Also alkaline hydroxides actually react with glass, to the fact that caesium hydroxide will munch through glass, the CsOH being at room temperature.
I love all the videos you and the team have it it over the years. I enjoy watching the reaction and having you explain what and how it is breaking down. It’s 🤩 amazing. I’m going to be practicing quick lime this winter to try and grow a winter crop I’m hoping it keeps them warm.
what about engines in a car that are all alluminum? Like a new Ford Mustang Gt? if I would pure that into a tank would that melt the engine or would it be diluted due to the amount of fuel in the tank. OR would it make it more active due to a combustion activity inside the engine?
NAOH pellets have been known to draw moisture in from the air around them to turn themselves into highly concentrated pastes. no other Hydroxide will do this. it is probably one of the most caustic substances known right now outside of radiotoxic compounds.
(0:13) I had no idea that Pepsi in the U.K. is in steel cans; they're all aluminium in the U.S. (2:10) The inside of the cans are also coated so their contents don't react with the aluminium, not as vigorously as your demonstration, but you wouldn't want to drink it.
What's absolutely amazing about this is, if you mix those highly corrosive substances together, the end result is just plain salt water! Assuming you've matched your ratios, of course.
if i recall,aluminum reacts better with acids in the presence of another metal, forming a weak battery. like if you put foil over a metal pan with acidic food in it, and it's touching both, it can melt the aluminum into grey sludge.. IRONically the pepsi can (since when are those made of steel?) might have helped.
Wonder about the molarity of each beside effective pH & reaction rate? Also would inks on label involve or catalyze this? Obviously each rather strong & interact since spectacularly evident in the real time rxn melt down! Definitely the most effective safety demo on hood use too! It's likely the most subtle & insidious are as harmful but that aren't really regarded as this demo shows.
+Bryan Foong The surface of the Aluminium is passivated and therefore, it's Al2O3+6HCl --> 2 AlCl3 + 3 H2O, I guess, but there still should be H2 somewhere
In science lesson when I was a put school I made dents & holes in my pencil tin & put hydrochloric acid on it & over the course of a few weeks the affected areas went all eaten & rusty. It looked cool.
Only steel ones. Depending on where and when they are made, they might use aluminum as well. . Where i live, the cans got a symbol specifying what material they're made of; if they don't where you live, perhaps it might be a good idea to start carrying a small magnet with you to test cans.
all can's are steel, because they are cheap, you will find they are only anonised or plated with aluminium, that's and depending on how, depends on whether it will be magnetic or rust, there is NO difference between pepsi or coke cans
The professor even said in one video that the American chemists agreed to stop calling it aluminum anymore. As an American I was pretty happy to hear about that.
I would guess that it does react but on the inside of the can theres a closed system and it's probably not a very violent reaction due to low concentration so a small layer of aluminum chloride would build up on the inside of the container shielding the rest of the aluminum from further corrosion. Similar to how most metals react with oxygen.
I'm doing my science experiment on seeing which metal resists corrosion the best after submersion in an acid. Do you have any tips on what acid I should use, and how long it would take for the acid to do anything?
Pretty much only because it's lighter. The protective coating aluminum metal develops from contact with oxygen from the air doesn't protect it from acids in soda and juice. That steel rusts more easily is actually a benefit for the environment, since steel cans left in parks, etc. will degrade quicker.
Can you explain what happens to the plastics? They should do a video about the chemistry of glass and why it is so safe for containing both acids and bases.
I use a cleaner that contains Sodium Hydroxide almost daily at my workplace. The safety precautions you're supposed to take when using it and the other cautions on the containers are ignored at your peril. it's very dilute, but when people get it on their skin because they're ignoring those warnings and procedures they always end up with nasty chemical burns. It's SERIOUS stuff.
Got to love youtube arguments. When someone realizes they are wrong, they nit pick how you phrased your argument instead of talking about the main point.
Does this mean that eating a piece of aluminium foil will react with the hcl in my stomach? What would the consequences be? Aluminium trichloride is probably not safe.
Ciroluiro Aluminium is toxic, the aluminium we use to wrap food or store it are not pure elemental aluminium, but a chemical compound. If you put aluminium foil into your stomach you might die or suffer a severe toxication !!!
@TheHumanParacite pH of aqueous solutions of acid are always extremely low pH because they aren't buffered, so it was probably about pH=1 or so. Likewise, the un-buffered solution of base was probably close to pH = 12
but wait, honest question here, the can very clearly reacted violently with the acid, but there is carbonic acid in all soda, shouldn't all (aluminium) cans of soda then slowly react with the contents until they rupture? does it have something to do with needing strong acids or bases, or is there some weird exception to carbonic acid acting like an acid? (sorry if this is dumb I am just finishing my first hon. chem in high school)
this is a cool experiment because anyone can do this at home, yes they are in undercover names, but you can by hydrochloric acid and sodium hydroxide, I personally have done both of these experiments.
@Kendrana I was thinking more about the NaOH and HCl present in the dishes on the video (wouldn't be as vigorous as solid + conc, but I don't know exactly how strong the reaction would be), but that's interesting... I remember being told really early in chemistry classes in high school that you always add the solid acid/base to water, never the other way around, because even the dissociation is exothermic enough to spray the highly concentrated acid/alkali everywhere.
The acid in cola is a Weak acid, H2CO3 (carbonic acid) is made from the CO2 in the soda + water. CO2+H2O==> H2CO3 Hydrochloric acid is the strongest acid with much Lower PH. hope this helps :)
I accept both pronunciations and actually do pronounce it Aluminum as I am American and have been saying that way my whole life. The problem I have is not that there is an American way and an English, my problem is with my fellow Americans thinking that our way is the only way and attacking others when they say it their way.
How do yo dispose of the mixture, you can't pour it down the drain because it would cause problems with the sewage piping. Would you try to make a ph 6?
VERY cool! My class doesn't seam to grasp that bases can be reactive, i tried putting hair in drain cleaner, didn't help. But this video is fantastic! what concentrations were used?
The reason why the can did better in acid is that soda itself is acidic. To prevent it from eating through the can the they have a special lining that repels the acid. So it is going to resist better to something it was designed to cope against. But you're right that they did leave out measurements and results might be skewed anyways.
Actually depending on the concentrations of the acid and base, seeing that the rate of reaction was relatively fast, the pH of HCl would actually be less than 0. Likewise he pH of NaOH would be greater than 14. It looked as if they were using high concentrations both definitely being over 1 M and because they are strong acids and bases they can "exceed" the pH scale so to speak.
Actually it doesn't matter what either country prefers. IUPAC decides what the standard names / symbols are for all elements and Aluminium is preferred / the original spelling. "Aluminum" was later accepted as a variant.
hmm.. but you have added different amounts of NaOH and HCl.. will both react at the same speed if you added same amounts of both?.. provided the concentrations are the same..
@sweetpopz As long as the cans are unopened I wouldn't worry as rust can only build in contact with oxygen (air), and that's presumably kept at bay by the CO2 in the drink (which makes the fizz).
at 9 years old I misunderstood a lot of words, but that's why we have the capacity to learn. I don't criticize British for saying "lorry" when I would say "truck" or "lift" when I would say "elevator" or "chockie" when I would say "chocolate" or "fancy a cuppa?" when I would say "want some tea?" because it's just a regional variation on the English language.

@TheHumanParacite pH of aqueous solutions of acid are always extremely low pH because they aren't buffered, so it was probably about pH=1 or so. Likewise, the un-buffered solution of base was probably close to pH = 12
but wait, honest question here, the can very clearly reacted violently with the acid, but there is carbonic acid in all soda, shouldn't all (aluminium) cans of soda then slowly react with the contents until they rupture? does it have something to do with needing strong acids or bases, or is there some weird exception to carbonic acid acting like an acid? (sorry if this is dumb I am just finishing my first hon. chem in high school)
What's the concentration and the total volume was used for both NaOH and HCl?
@periodic videos
what was the strength of the acid and base that you used?
this is a cool experiment because anyone can do this at home, yes they are in undercover names, but you can by hydrochloric acid and sodium hydroxide, I personally have done both of these experiments.
@Kendrana
I was thinking more about the NaOH and HCl present in the dishes on the video (wouldn't be as vigorous as solid + conc, but I don't know exactly how strong the reaction would be), but that's interesting...
I remember being told really early in chemistry classes in high school that you always add the solid acid/base to water, never the other way around, because even the dissociation is exothermic enough to spray the highly concentrated acid/alkali everywhere.
The acid in cola is a Weak acid, H2CO3 (carbonic acid) is made from the CO2 in the soda + water. CO2+H2O==> H2CO3
Hydrochloric acid is the strongest acid with much Lower PH.
hope this helps :)
Quick question what would happen if you drank a base? like the one they used in the video
I accept both pronunciations and actually do pronounce it Aluminum as I am American and have been saying that way my whole life. The problem I have is not that there is an American way and an English, my problem is with my fellow Americans thinking that our way is the only way and attacking others when they say it their way.
How do yo dispose of the mixture, you can't pour it down the drain because it would cause problems with the sewage piping. Would you try to make a ph 6?
VERY cool! My class doesn't seam to grasp that bases can be reactive, i tried putting hair in drain cleaner, didn't help. But this video is fantastic! what concentrations were used?
The reason why the can did better in acid is that soda itself is acidic. To prevent it from eating through the can the they have a special lining that repels the acid. So it is going to resist better to something it was designed to cope against. But you're right that they did leave out measurements and results might be skewed anyways.
Actually depending on the concentrations of the acid and base, seeing that the rate of reaction was relatively fast, the pH of HCl would actually be less than 0. Likewise he pH of NaOH would be greater than 14. It looked as if they were using high concentrations both definitely being over 1 M and because they are strong acids and bases they can "exceed" the pH scale so to speak.
Actually it doesn't matter what either country prefers. IUPAC decides what the standard names / symbols are for all elements and Aluminium is preferred / the original spelling. "Aluminum" was later accepted as a variant.
@iamsamg there are no such strong acids and bases in the kitchen, and the coke's pH is lower that 7 but is a very weak acid to react with the can
hmm.. but you have added different amounts of NaOH and HCl.. will both react at the same speed if you added same amounts of both?.. provided the concentrations are the same..
@sweetpopz As long as the cans are unopened I wouldn't worry as rust can only build in contact with oxygen (air), and that's presumably kept at bay by the CO2 in the drink (which makes the fizz).
is the reason for the less destructive reaction with acid the oxide layer over aluminium?
@mac5565 NaOH is a base. Because it soluble in water it is also an alkali.
at 9 years old I misunderstood a lot of words, but that's why we have the capacity to learn. I don't criticize British for saying "lorry" when I would say "truck" or "lift" when I would say "elevator" or "chockie" when I would say "chocolate" or "fancy a cuppa?" when I would say "want some tea?" because it's just a regional variation on the English language.
