This video is hands down the best pH video on KZbin. 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.

[@Socratica]

+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!

[@mariojayaweera5671]

Will do.

[@Socratica]

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!

[@ImD1v1ne]

Didn't even help me calculate the pH of a solution when the molarity is given.

[@razz023]

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.

[@taylor_eqq]

Chemistry is NOT my strong suit and I have a test tomorrow. This helps me so much

[@Socratica]

We're rooting for you!! 💜🦉

[@waleedaldikhary]

Great video, I loved the simplicity of your narration.

[@soilsurvivor]

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 ...)

[@bonbonpony]

What was the wrong way?

[@jayapiriya3870]

Gud pls update some more videos in chemistry as I am a neet student Very nice explanation ....keep rocking...

[@anarvalehli3683]

best ph video in youtube for sure

[@Socratica]

You're too kind, Socratica Friend!! 💜🦉

[@LucianoJuly]

Yup, best ph video I’ve seen…nice!

[@mortezahabibnia8120]

Thanks for your great presentation.

[@robinff3499]

Thanku so much.... ❤ Today is my test and I'm watching this on my bus stop😅

[@Socratica]

Good luck!! Let us know how it goes!! 💜🦉

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

[@footballshorts248]

Very very clear. Thanks. Though I'm not a Native Englishman, I understand it very clearly.

[@lukem3724]

This was very very helpful yo. Thank you.

[@emilycottman]

Great. Thankyou so much. Makes it so simple for me when I can watch and listen rather than read from my text book! :)

[@Socratica]

+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! :)

[@emilycottman]

+Socratica :) I'd be really keen to see a video on pKa & pKb and how they relate to each other and pH. Thanks!

[@279-adinciocosta8]

Thank u very much to make it so simple

[@bonbonpony]

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?

[@elliejenneh3051]

This video is the best

[@morpheus9515]

omg its really amazing work . thank you a lot

[@vickash1072]

why doesn't soda (Coca Cola) damage you mouth as much as a cleaning acid with same pH ?

[@vignesh0208]

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.

[@Socratica]

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!

[@sakthivelkarthick2226]

Great video. It was really nice. Keep it up

[@kartiktaneja7868]

Very thankful everybody

[@syrekongen982]

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?

[@BagpackTraveler]

I don't know how u calculate to the end result of pH pls show d calculation

[@micrationart9681]

Nice explanation

[@nairobianniccur2003]

i think everyone should watch this video it has alot and it helps

[@Jelleydev]

socratic app be hitting diff ngl

[@NatalineJ]

Wonderful. Thank you.

[@blackhawkX02]

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 :)

[@Socratica]

That's great to hear! Good luck with your studies. :)

[@blackhawkX02]

Socratica Thanks for your videos! :)

[@khanpkkhanpk3153]

Thanks for the best of the best video

[@aroojshah2642]

best video on pH🤗🤗🤗

[@jivvala824]

Best video made to explain the concept of pH in less time.

[@ZeidGho]

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 😢

[@angelicapaa9402]

Thank you!

[@celebritystylewatch]

I would like to say "excellent".

[@shagunsen8568]

Thanks but can u tell me that how did you calculated the maths part. I didnt understand.

[@edwardhaughney9665]

Yep this is one of those upper eschelon videos. Right up there with that Socrates guy. Good work

[@tnyahhopson185]

How did you get 2.5 for example 3

[@anna-wt2tz]

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

[@ajaymishrakumar]

Thanks it's help me a lot..

[@wakkowarner7391]

Who's mouth started watering when the lemon showed up?

[@Socratica]

They're so delicious!! 💜🦉

[@mansooranwar4093]

Great . Thank you

[@ikyhwh]

I failed trig twice. Got lost at -log but I understand that it's a constant and measurable relationship to hydrogen ions.

[@AakashKumar-cm5bm]

Best information

[@informing_]

Nice thanks

[@christopherscottgutierrez3323]

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

[@leidibugz]

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.

[@joannescalzitti9959]

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.

[@mahadow1]

The best video about pH 👏

[@mahadow1]

Thanks indeed 🙏

[@FAZBAZ728]

how did you get to 3.16x10 to -9???

[@ericferro510]

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)

[@Socratica]

What a great idea for a follow-up video! Thanks so much for your interesting comment, Eric. We're glad you're watching!

[@vinaykumarsonti3186]

[@samirthapa6145]

Thanks

[@Luzt.]

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).

[@Socratica]

Good point, Luzt! More of an anecdote than an always-true kind of thing. :D

[@CarayMay]

Detergent, ya basic.

[@Socratica]

Heeee!!!! 💜🦉

[@Fruit_Sandwich_]

I’m 10 :/

[@opdking4024]

Why don’t they start the video off with what it stands for

[@trainingporpoises.]

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.

[@anacondaeunectes1854]

Useless. Starts off with non layman terms. What does "pH" stand for?

[@trainingporpoises.]

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.

[@b_d_bubbles]

Im writing my exam tomorrow, and this did justice tbh.❤️‍🩹🫶🏻

[@Socratica]

GOOD LUCK!! 💜🦉
