This video is hands down the best pH video on UA-cam. It teaches you pretty much everything in 8 minutes! I overlook videos like these because they have much less views than the rest so I assume that they aren't that great- I was wrong.
+Mario Jayaweera, we're so glad you've found our videos! We do put a lot of work into them and it is truly cheering to read a nice message like yours. If you can, please share with your friends - then we can grow, and more people will get to learn!
I would say just wow. So simply explained and in a relatively short time. Chemistry has been a nightmare for me but such videos make it look easy. Thanks a lot.
This video made me realize I'd learned pH the wrong way, in high school. Consequently, I struggled with acid-base chemistry, and chemistry as a subject area became something to be avoided. Thank you for taking the blinkers (blinders) off!! GREAT video!! (Trying to see if you have one on red-ox reactions ...)
1. Ph is a way to measure the strength of acids and bases 2. An Arrhenius acid is a substance that generates H+ ions when dissolved in water 3. Bases when dissolved in water generate OH- 4. We use the Arrhenius definition when dealing with aqueous solutions of substances 5. The brønsted-Lowry is based on the transfer of a proton, an H+ion, from one substance to another 6. A brønsted-Lowry acid releases a proton 7. A brønsted-Lowry base accepts a proton 8. The brønsted-Lowry definition does NOT depends on substances being dissolved in water 9. A strong acid more readily donates a proton than a week acid 10. A strong base more readily accepts a proton than a weak base 11. The pH scale was suggested by Søren Sørensen 12. It’s a logarithmic scale that makes it easier to write the very small amounts of H+ ions that are produced by acids and bases 13. The equation is: pH=-log[H+] 14. Water is neutral 15. All substances that have a pH of seven are neutral
I don't understand. As far as I understand ionization, it is the loss or gain of electrons therefore changing the charge of the atom. Right? How do protons come into play in this definition of pH?
+emilycottman Thanks for your nice comment! We're so glad we could help! We'd love to hear what other topics you would like to see. Good luck in chemistry! :)
I have some practical questions: can we change the pH of something? How? For example, if we mix baking soda on a glass of lemon juice it becomes more neutral? And, doesn't the pH of the land where the lemon was harvested influence the pH of the lemon itself? I'm far from being a scientist or even having a scientific mind, I'm just curious.
You can change the pH by adding acid or base, depending upon whether you want to make something more acidic or basic. Neutralizing lemon juice with baking soda occurs because baking soda is like a towel that soaks up H+. This is possible because a base, by definition is an H+ acceptor and an acidic substance like lemon juice is acidic because it gives up H+. The pH of soil affects many things such as phosphate availability, but not the acidity of the lemon. A lemon is acidic because it forms a lot of citric acid.
02:32 But doesn't it produce the "basic" OH⁻ ion at the same time? :q Because if that's the case, this animation/explanation wouldn't explain the _excess_ of H⁺ ions in the solution, would it? 04:40 Why are the concentrations being multiplied here and not added?
the volume of the acid is the same mole for the absorbed substance, the acid level will drop with other moles that are not absorbed as well or vise versa absorb same or better it will go up, like water you put your finger in it it will drop acidic level due to other moles that are not absorbed as well for the human body, if you osmos the water it will go up in acid level if you osmos right for the human body abosorbtion
This was uploaded in 2015, and so few views. Your lectures are underrated Socratica. You explained the concepts in the most simple and concise manner. Kudos.
Thank you so much for your kind comment. It's the fact that people like you are still finding our videos and finding them useful that inspires us to keep making more!
Really, the best video on pH, but there was one thing that remained unexplained and I think it's of major scientific interest in what regards the study of acids and bases, it is: what's the physical and chemical properties and processes that produces the macroscopic phenomena of corrosion when an acid enters into contact with other substance, let's say, a metal... (Like in the reaction HCl(aq) + Fe(s) --> FeCl + H)
Great video. I'm not sure thou about the relation between "liquid being slippery" and it's Ph. I bet there may be here (loosely defined) correlation but not causal relation (e.g. not all basic solutions must necessarily be slippery).
because the term "potential of hydrogen" doesn't make sense to beginning chemistry students. It's an archaic phrase that people used to use a long time ago.
Does it really make you understand more if someone tells you it stands for "potential of hydrogen?" that is the real jargon and that isn't going to make any sense to anyone. Watch the whole video, it tells you everything you need to know.

Will do.
Hooray! We'd love to hear what other topics you'd be interested in as well - we're making new videos all the time. Thanks for watching!
Didn't even help me calculate the pH of a solution when the molarity is given.
I would say just wow. So simply explained and in a relatively short time. Chemistry has been a nightmare for me but such videos make it look easy. Thanks a lot.
Chemistry is NOT my strong suit and I have a test tomorrow. This helps me so much
We're rooting for you!! 💜🦉
Great video, I loved the simplicity of your narration.

Gud pls update some more videos in chemistry as I am a neet student
Very nice explanation ....keep rocking...
Thanku so much.... ❤
Today is my test and I'm watching this on my bus stop😅
Good luck!! Let us know how it goes!! 💜🦉
best ph video in youtube for sure
You're too kind, Socratica Friend!! 💜🦉
Yup, best ph video I’ve seen…nice!
why doesn't soda (Coca Cola) damage you mouth as much as a cleaning acid with same pH ?
Thanks for your great presentation.
socratic app be hitting diff ngl
I don't understand.
As far as I understand ionization, it is the loss or gain of electrons therefore changing the charge of the atom. Right?
How do protons come into play in this definition of pH?
Very very clear. Thanks. Though I'm not a Native Englishman, I understand it very clearly.
Great. Thankyou so much. Makes it so simple for me when I can watch and listen rather than read from my text book! :)
+emilycottman Thanks for your nice comment! We're so glad we could help! We'd love to hear what other topics you would like to see. Good luck in chemistry! :)
+Socratica :) I'd be really keen to see a video on pKa & pKb and how they relate to each other and pH.
Thanks!
i think everyone should watch this video it has alot and it helps
I don't know how u calculate to the end result of pH pls show d calculation
Excellent Video!
Thank you for watching! We're so glad to hear it helped! 💜🦉
Thanks but can u tell me that how did you calculated the maths part. I didnt understand.
How did you get 2.5 for example 3
did you figure it out? I've done it a few times but I have no idea how to get 2.5 in this example, my answer was -0.0316
I failed trig twice. Got lost at -log but I understand that it's a constant and measurable relationship to hydrogen ions.
This was very very helpful yo. Thank you.
Thanks, i need to stick to the topic for longer but i think i got the basic idea of what it is and those examples helped :)
That's great to hear! Good luck with your studies. :)
Socratica
Thanks for your videos! :)
Very thankful everybody
Thank u very much to make it so simple

Best video made to explain the concept of pH in less time.
I would like to say "excellent".
Who's mouth started watering when the lemon showed up?
They're so delicious!! 💜🦉
This video is the best
Great video. It was really nice. Keep it up
omg its really amazing work . thank you a lot

Yep this is one of those upper eschelon videos. Right up there with that Socrates guy. Good work
how did you get to 3.16x10 to -9???
Thanks for the best of the best video
6:32
Are u from america
Thanks it's help me a lot..
In High School I got 100% in math, 100% in physics, and 39% in chemistry! That was 13 years ago, and I still don't understand a thing 😢
Thank you!
best video on pH🤗🤗🤗
In which lesson
Great . Thank you
Nice thanks
Please do thermodynamics
Where you find H+ value??

What a great idea for a follow-up video! Thanks so much for your interesting comment, Eric. We're glad you're watching!
will u please upload a total summary about chemical bonding...its so hard to learn and understand
Best information
What is PH. 0 & 1
doesn't that stand for po-
The best video about pH 👏
kia negative pH hoti h AGR hoti h to q AGR nhi hoti to q nhi hoti
what is the ph value of Hcl with the concentraion 1*10^-9??? Please ans me...
Kavin thanu would you still like an answer to that q?
You don't say how you justify water ionization is minimal. Not science.
Vídeo muito bom... Eu vivia tentando entender isso kkkkkk Faz mais em português, por favor :D
Sorcratica ,my drink is ph6
What is the Ph of 10M Hcl???
69
Wait coffee is acidic!? Then what's up with the bittery taste ?!
Also thanks for explaining the ph
Yes. Mr.intellectual but dont stop to take coffee
How t use log in ph
show video pH value not in decimal
Thanks indeed 🙏
Thank
Seawater is more surprising to me
I feel smart
Thanks for help....;)

Great
thnks
How u solve the pH of soda from 3.16*10^3=2.5
yes, this is the part I'm currently struggling to understand, howd she get 2.5
Great video. I'm not sure thou about the relation between "liquid being slippery" and it's Ph. I bet there may be here (loosely defined) correlation but not causal relation (e.g. not all basic solutions must necessarily be slippery).
Good point, Luzt! More of an anecdote than an always-true kind of thing. :D
I have test today and idk 💀💀😫anything
Thanks

Why am I drinking pickle juice to get rid of heartburn.
Milk 🥛 😲
I’m 10 :/
Why don’t they start the video off with what it stands for
because the term "potential of hydrogen" doesn't make sense to beginning chemistry students. It's an archaic phrase that people used to use a long time ago.
Useless. Starts off with non layman terms. What does "pH" stand for?
Does it really make you understand more if someone tells you it stands for "potential of hydrogen?" that is the real jargon and that isn't going to make any sense to anyone. Watch the whole video, it tells you everything you need to know.
