Vinegar may have a powerful smell, but did you know it's actually a weak acid? In the chemical economy, acids actively give away their protons while bases actively collect them -- but some more aggressively than others. George Zaidan and Charles Morton use the currency of subatomic particles to explain this unseen exchange.
Lesson by George Zaidan and Charles Morton, animation by Karrot Animation
Those weak acids and bases is how I feel now in AP chemistry
Eh uh, I'm taking AP chem this year :{
+Pat rick I wish you all the luck in the world, I finished it and it was awful... The teacher who taught the class is wicked old and the science department has been trying to get rid of him for years. We actually did so bad this year that they demoted him from teaching AP chemistry next year.
+Kristi Shanshan yikes, unfortunate. Was your AP chem class in HS?
+Pat rick yes, I took it junior year, should have taken AP Biology instead
This is TH-cam not a messaging app ._.
George Zaidan's TED lessons simply have the best music, best animation and best narration. Keep up the good work!
that's really nice
which is more than I can say for beeeeeeeeeeeeeeeeeeep
wah wah
honestly best part

@Low End Gamers hahahahahahahaha
I thought my science / homeroom teacher edited that in while we we’re watching this in science class but I didn’t know it was in the video! 😂
Great explanation and couldn't have had a more hilarious ending.
I'm 29 years old, and have run through units on acids and bases within multiple classes throughout my life. I sit down for 10 minutes to watch this vid, and it all finally makes sense. I'm so relieved and pissed off at my education background.
Still helping students after 10 years, what a legend
What the hell happened at the ending? xD Suprising.
I don't know but I love it
lol, I sure was surprised!!
What was the word? All the swear words ik dont fit, at least i dont think they did….
@@Daytime_Scars it’s not a swear word, it was referring to something they can’t say on TH-cam. Most likely something that would have gotten them canceled. They were also referring to not being open 24/7, charging interest on out molecules?? Maybe US Healthcare?? I may be very wrong but it’s just a thought.
i was told that its the name of a banking company that they bleeped out
Good point. Nucleic acids (DNA or RNA) are actually amphoteric, meaning they can act as both an acid or base. The basic component is, as mentioned, the nitrogenous base (A/T, G/C) and the acid component is the Phophate group. In the case of DNA, the bases are in the interior while the acidic phosphate groups on the exterior thus the acidic component of DNA is more prominent than it's basic component.

Very well done! Beautifully animated and incredibly eloquent.
"Solute water" is a strange but clever pun.
oh
OH.
Waah - Waah
Why
Just love the amazing team of Ted.Ed...keep posting❤❤
Fantastic explanation! Love the animation.
Remember how water is a molecular ATM next time you drink some. You're drinking liquid ATMs.
Dafuq
Liquid money
Nice!
Liquidated assets.
this is so good!!!! i understand it perfectly and the analogy with the ATM MACHINE was *chefs kiss*
As a chemist...I still have PTSD from Organic Chem😭😭 ughh the tests were horrid
Love this whole thing, especially the ending lol.
How are protons exchanged? I thought only electrons were transferred.... Aren't protons always "stuck" to the nucleus?
+Alduin, Firstborn of Akatosh A hydrogen ion has no electrons and only 1 proton in the nucleus with no neutrons. Essentially, a hydrogen ion is just a proton. That's why we say acids donate protons (lose a hydrogen ion) and bases accept protons (take in a hydrogen ion).
Thanks a lot that helped me!
Andy Chen thanks!
Alduin, Firstborn of Akatosh Easy, make the atom "A offer he can't refuse"
Ha the video has a wrong explanation
Loved this episode!
very nicely and neatily describe everything in detail
That was an amazing, clear video. Thanks :)
OMG. The animation is SO CUTE. XD The flasks! I want one!!!
I just started learning this today, and you have a video :O
What a great and educational video!!!
because of this video I uderstood the hard concept of acid base thnxxx ted ed
love this narration!
Well done. The narrator does a good job of explaining. Still wish I had someone to help step me through this
Nice explanation!
Depends on the physiological pH and thus what compartment of the body we're referring to. Amino acids do not always have both groups charged.
I loved the animation and graphics♥️😘
Excellent ending. ...excellent.
Animation is TOP NOTCH ! 🏆🏅
you covered all the bases in this one.
underrated comment
great video
So simple to understand
What was the company under the bleep? Was that aimed at a specific company or a generalization of many companies ?
the end omg i didnt expect that at all
Again this animator is legandary!Does anyone know which program(s) are used?please reply!
DROP THE BASSSEEEE!!!
Dropping acid! Sounds like a party to me!
I
You made it sound like a bad thing.
*NOT BEFORE YOU'VE DROPPED THE WATER!!!*
On the floor?
Excellent
The strength an acid or base depends on what the solvent (or another reactant) is. For example, nitric acid/HNO3 is a strong acid when placed in water/H2O. However, if we switch the solvent to sulfuric acid/H2SO4 (which is a stronger acid than HNO3), sulfuric acid will "force" the nitric acid to act as a (weak) base. So the strength of an acid isn't affected by "how" diluted it is, but rather by "what" it's being diluted by.
Yay to water, you will always be the universal solvent in my book! who would have ever thought that a two part hydrogen, and a one part oxygen molecule would posses such wonderful characteristics!
THANK YOU

It's very nice video
Gah I love these videos! Their cute, educational, and entertaining :D
wah- waah indeed.
Oque Acontece que misturamos ácido com base?
This is the bane of my existence... exactly why I'm going to major in music performance and not chemistry 😂😂
Oh dang, I just checked and you are right. I could have sworn. Well I guess I shouldn't trust my memory so much, my chemistry classes go way back. Sorry for my mistake.
Cn anyone make a vdio on plant reproduction and electronic components eg:-transister and there properties.
Can anyone tell me about the molecules that behave like acids or bases without water?
yes
"it doesn't take much to be an active player in the chemical economy" wise words
I NEED THE BACKGROUND MUSIC PLEASE!!!!!!!!!! What is it??
and what are the facors that make it fully or partially donate proton ?? or what are the factors that make it weak or strong ?
Codo Sacho
Mostly the stability of the compound itself or its conjugated form (that is base + proton or acid - proton) is what decides weak/strong. If the conjugated base (acid - proton) is more stable because it can spread its negative charge more easily in its structure (Cl- ), it will donate a proton faster than one which does not have that option(H2PO4- ). In fact, you can even turn the terminology around in that the conjugated base of a strong acid is a (very) weak base. A very weak base would be unable to take protons from water meaning no increase in pH. This is a roundabout way of proving that the strong acid was, in fact, strong.
In reality the acid has to be more eager to donate its proton than hydronium (H3O +), thus more so than protonated water.
what software for making this vid ? anyone know ?
word document
Ae?
Or Fl
i make these in Excel
what was he trying to say on the beep
reminds me of how screwed i am for hsc chemistry..
What about those ones that can act as acids or bases without water? Can anyone please point to a video (or maybe just explain it)?
goose121 they all are acids or bases WITHOUT needing water. The water is just most times used to show the reaction the acid and base because water if right at 7 pH, neutral. Basicly, think of acid and base like cars. There are some that go fast and slow but they all need fuel to actually show what they can do. And for acid and base, the fuel is anything. But water is just used mostly ba use its neutral
For glycine the pKa's are 2.35 and 9.78, so apart from the stomach, it's pretty rare.
bepis
they behave by the way we define it,
Brønsted-Lowry acid/base are proton donor/receptor
lewis acid/base don't necessarily need water, as their definition is based on electrons, not protons
Omg youtube recommended me this and I have a chemistry test on this stuff. Coincidence? Idk I’m creeped out rn 😱😱😱
umm ok.... thats not that special... thats normal don't be surprised lol
And the same thing applies with Amino acids, meaning they're amphoteric too. This is b/c they have both an acidic carboxyl group and a basic amino group.
nerd
more concentrated not 'stronger' as a mole of that substance still gives or takes the same amount of protons
It depends on what you mean by acid here. In coloquial use, acid usually refers to an acidic solution, in which case the more dilute it is, the weaker the acid is. However, when chemists talk about acids, they talk about pure substances rather than solutions, whose acidity is independent of their concentration.
nerd
Sulfuric acid is a strong acid. Its conjugate base, hygrogen sulfate, is a slightly weak acid.
I love the voice actor. The sass
I'm not getting your point here. I said that amino acids are amphoteric (more specifically amphiprotic), which is most assuredly true in their more common zwitterionic forms due to their protonated amine group able to act as a B-L acid and their unprotonated carboxyl group able to act as a B-L base.
I AM SO READY TO GIVE OUT PROTONS. TAKE MY PROTONS NOW!
It doesn't matter if the N terminus or C terminus ends are protonated or not. They're still called "amino" and "carboxyl" groups.
I don't get the ending. Why was he bleeped?
It's the name of a bank
more then you can say for most banks?
I think my original point was that amino acids neither contain an amino group, nor a carboxyl group, unless included in the side chain, or at least not under the same conditions.
More chemistry
This is a very good explanation though he kind of combined the lewis and bronsted definitions, purposefully I assume, for simplicity.
Didn't expect that ending,🤣
Unboxing video coming soon! #QUEST

What do you mean protons also known as hydrogen ions?? I dont understand, they are different.
Hydrogen is basically one proton and one electron and when it becomes a ion it looses a electron leaving it with one proton without electron nor Neutron.
I am not highly educated person on topic but this is best way I could explain :)
@@mmuslih7955 thank you! and I understood your explanation clearly 👍🏼👍🏼
The end. Hilarious!

does anyone know how to put this video into a document. PLEASE HELP
What kind of document?
just put link instead and the thumbnail (google image search this video for thumbnail)
Bell ding ding!!!
Why should clean the hydrochloric acid with a towel and no water ? And whys is more important do that with the hydrochloric acid than with the carbonic?
you can add acid to water. but never add water to acid. the water will stay on the surface of the water and bubble up and boil. it will spurt out at you and could give you really bad burns
Is a base the American word for alkaline? Because the way you described a base sounds a lot like how you describe an alkaline
Tad Strange alkalines are bases which are soluble in water
Thanks!
What happened at the end?!?
DNA consists of units eacht divided into three portions:
D: a deoxyribose sugar, the primary structural component,
N: a nucleobase, giving each unit its identity,
A: a phosphate group, linking units together and giving them their acidic character
nerd
The ending was awesome.
So were you, sweaty ;)
@@wordsforwounds WTF
awesome!
epic lawlz0r xDDD
Wasn't it the opposite? The difference isn't about electrons and not protons?
I didn't get the end. Someone able to explain it ?
Omnilatent the writer of the script has had personal issues with a certain bank but he cannot say it on video as the video would get taken down. So they censored it.
