🎯 Key Takeaways for quick navigation: 00:01 🧪 Acids can be identified by having a hydrogen in front of them, while bases typically have a hydroxide ion or a hydrogen attached to a metal. 01:34 🧪 Arrhenius acids release H+ ions into solution, forming hydronium ions, while Arrhenius bases release hydroxide ions. 02:21 🧪 Bronsted-Lowry acids are proton donors, bases are proton acceptors in acid-base reactions. 03:40 🧪 In reactions, conjugate acids form from bases, and conjugate bases form from acids. 06:36 🧪 The pH scale measures acidity: pH < 7 is acidic, pH = 7 is neutral, and pH > 7 is basic. 07:19 🧪 pH + pOH always equals 14 at 25°C. H3O+ concentration = 10^(-pH), hydroxide concentration = 10^(-pOH). 07:55 🧪 Strong acids fully ionize, weak acids partially ionize. Strong bases are soluble and fully ionize, weak bases do not. 08:38 🧪 Common strong acids include HCl, HNO3, H2SO4, and HClO4. Weak acids include HF, and most others. 09:50 🧪 Oxyacids follow a trend: more oxygen atoms make the acid more acidic. 10:38 🧪 Strong acids produce hydrogen gas when reacting with metals; weak acids do not. 12:03 🧪 Strong bases fully ionize in solution, while weak bases only partially ionize. 14:24 🧪 Water can act as an acid (donate H+) or a base (accept H+), making it amphoteric. 18:40 🧪 Acid indicators turn blue litmus red, base indicators turn red litmus blue. 20:38 🧪 Acids react with active metals to produce hydrogen gas; not all metals react with acids. 21:52 🧪 Ka is the acid dissociation constant, while Kb is the base dissociation constant. 23:44 🧪 Water's autoionization, where water molecules act as both acids and bases, is described by the Kw expression. 25:44 🧪 Amphoteric substances can act as both acids and bases depending on the reaction conditions. 29:11 🧪 The ion product of water (Kw) is temperature-dependent and equals 1 x 10^(-14) at 25°C. 30:06 🧪 pH and pOH equations depend on temperature; usually assumed 25°C. 30:48 🧪 Ka * Kb = Kw at 25°C (1e-14); useful for calculating Kb from known Ka. 31:30 🧪 Various equations interrelate pH, pOH, Ka, Kb values. 32:29 🧪 Calculating pH from H3O+ concentration using -log formula. 33:09 🧪 pOH calculation and its relationship to pH (pH + pOH = 14). 33:39 🧪 Hydroxide ion concentration calculation from pOH. 34:11 🧪 Calculating pOH from hydroxide ion concentration. 34:45 🧪 pOH estimate based on exponent for weak acids or bases. 35:07 🧪 Calculating H3O+ ion concentration from pH. 36:29 🧪 Calculating hydroxide ion concentration from hydronium ion concentration using Kw. 37:39 🧪 Calculating pKa from Ka (negative log of Ka). 38:50 🧪 Calculating pKb, then Kb from pKb (pKb = 14 - pKa). 40:51 🧪 Identifying true statements about acids and bases. 45:11 🧪 Understanding acid strength based on Ka and pKa values. 52:20 🧪 Definitions of acids and bases by Arrhenius, Bronsted-Lowry, and Lewis. 56:01 🧪 Lewis acid-base interactions involve electron pair transfer. 57:45 🧪 High positive charge metal ions act as Lewis acids; bond with lone pair electrons.
My maths teacher took 3 months to explain the bonds, to such an extent I started to abhor it. And this lifesaver teaches it to me perfectly in the span on 2 hours. Good god, would be somewhere else if my sis didn't recommend this yt channel
Dude my teacher took 3 periods to explain, I didn’t get it, even when I went to extra help everyday I still didn’t understand but the second I clicked on your video it just came out. It came out. Thank u so much man I love u way more than my BF Aidan Hong who fails to explain any chemistry :(((.
I sit in lectures, tutorials, try to revise online from past lecturers yet none of my university lectures have explained any of these to me. They just expect us to know. Thank you so much for putting in the time and dedication in teaching us all 🙏 You've helped me out so much.
Uni??? Bro we are taught this stuff and are supposed to know it and I am not even in high school(senior secondary in India ) yet I’ll be in highschool next year
Great basic intro to acids and bases. I show it to students I tutor in chemistry (especially visual learners). I encourage them to turn on closed captions, stop the video if needed and take notes as he teaches. Thank you Organic Chem Tutor!
You are such a life saver! I am studying for my TEAS exm and I have learned a lot from you. I will definitely watch more of your videos to understand the Science portion for the exam.
AMAZING!! You are saving my butt in the acids and bases topic. My mind was blown when you broke down what ka, kb and kw meant!! WOW who knew it be THAT simple?!?! THANK YOU ORGANIC CHEM TUTOR!!! You are my go to :)))
Professor Organic Chemistry Tutor, thank you for a tremendous Introduction into Acids (strong and weak) and Bases (strong and weak) in AP/General Chemistry. The overall explanation of the properties of acids and bases are exceptional from top to bottom. Calculating the PH and POH are important for different acids and bases in Modern Chemistry. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
You helped me get through general chem. Thanks a bunch and you are the best. Enthalpy and entrophy were tough until you explained them. Outstanding work!!!!
I will be taking my last chemistry board exam tomorrow. This has been an absolute lifesaver. I have been referring to your videos since I was in 7th grade. Now being in 10th I would like to thank you from the bottom of my heart!!
thank you for teaching me more and more thoroughly in one hour than in 3 weeks of my 2x weekly, 2 hour lecture. Seriously. I'm just going to skip my lectures >_>
Thanks a lot for this video on Acid bases and salts....i really appreciate it..may God continue to give u more wisdom knowledge and understanding to impact ur intellectual knowledge on us God bless you Thanks again ☺️👍
my textbook just defined acids, salts, bases and hydroxides in 3 lines -.- I'm so thankful for an explanation in which I actually get the information to identify them. Thank you!
12:28 are you sure aluminum hydroxide is a base? beacuse not every hydroxide is a base and I think that's Al (OH) 3 has amphoteric properties. correct me if Im wrong :)
I'm a bit confuse a "time stamp" [48:00] Yes i know that -1 > -2 so on and so forth, but in this case that -1 is greater than -2 that means minus 2 is has a low value than 1. But, isn't that an acid level is higher when they reaches lower level? Could you please elaborate.

I TOTALLY AGREE 💀💀💀💀
My test is tomorrow on Monday, it’s the last thing for chemistry
Me too, I literally have hours to go
This man’s taught me organic chemistry. I’m here to update that I passed my OChem course! Thank you.
congrats! what grade did you make?
@@leomiller2291 I got a B, and my professor said “I hope you’re happy with your grade” and HECK YEAH I WAS WOOOP WOOOP!!! 🕺

This guy's videos is saving humanity. He is the godfather of man kind.
In a week I'm taking my chemistry exam, and I've watching your videos to study so that you for explaining in more detail tha. My actual teacher
My brother recommended you to me and since then, I've never had any regrets knowing this channel😊
Im so cooked it’s genuinely over
ong i have h chem final tmrw nd i just happened to miss the class going over this
😂😂😂,it's chaai
Failing CHEM 264 as I speak
My useless teacher completely fucked over my grades in science. I understand physics but chemistry. OHHH HELL NA
“NEVER BACK DOWN, NEVER WHAT? 🗣🔥🔥🔥”
No amount of money can match the help you give us ,We love you.God bless you for us .
You are such a life saver! I am studying for my TEAS exm and I have learned a lot from you. I will definitely watch more of your videos to understand the Science portion for the exam.
lightsaber cheerio
I am so happy this fella exists i would be failing chem without this king
i swear this guy is the only reason I have straight a's in class
You singlehandedly saved my chem grade thanks a lot man
He's better than my teacher... you changed my whole life !!😊
In what I typically need to learn in one week I learn in one hour by watching your vids.
because of this guy, i am now accepted to harvard, jesus christ I never thought i would go this far
Congratulations bro 🎉
🎉🎉🎉
congrats brother🥳🥳
SLAYED
The way he teaches good, I think am going to learn chemestry from him for knowledge.
Chemistry**** 😁😁
AMAZING!! You are saving my butt in the acids and bases topic. My mind was blown when you broke down what ka, kb and kw meant!! WOW who knew it be THAT simple?!?! THANK YOU ORGANIC CHEM TUTOR!!! You are my go to :)))
We're not yet here, but thanks bro allot all of ur videos helps me allot.
also by the way I like ur voiceits very soothing and very cool to hear

Yo that -log trick with looking at the exponent to predict pH is so helpful
You helped me get through general chem. Thanks a bunch and you are the best. Enthalpy and entrophy were tough until you explained them. Outstanding work!!!!
How can I get the video on this topic?
The most beautiful explanation I've ever seen in ma life👌🏼💗
Man u teaching physics and chemistry makes me understand better than my teacher even in a decade
Thank you for being a better teacher,I now understand more than what I learnt in class,you are the best
I will be taking my last chemistry board exam tomorrow. This has been an absolute lifesaver. I have been referring to your videos since I was in 7th grade. Now being in 10th I would like to thank you from the bottom of my heart!!
man watching ur video for 3 sec is much worth than wasting whole day at school thank you you making alota students better all over the world
thank you for teaching me more and more thoroughly in one hour than in 3 weeks of my 2x weekly, 2 hour lecture. Seriously. I'm just going to skip my lectures >_>
I wish my Chem teacher was as good as you man
Man is in hammer bam bam bam!!
If you are reading this, I wish you all become successful, I can't wait to see the success of you all 💕
Thanks
Thank you
You are amazing! Carried me all the way through intro chem and I have a 95 % still ! ❤
Taught me more in 58 minutes than my actual teacher could in a week😅😅
I honestly wouldnt pass first year eng without you
Thanks a lot for this video on Acid bases and salts....i really appreciate it..may God continue to give u more wisdom knowledge and understanding to impact ur intellectual knowledge on us
God bless you
Thanks again ☺️👍
You're the greatest I've seen on UA-cam 🥺🥺🥺🥺🥺🥺🥺🥺 you teach chemistry like ABC so easy to understand
Hey thanks for your videos I got an A in chem 2! I’m still gonna use you for Physics tho 💕
Thanx am somewhere at least
keep it going!
god bless your soul because i have my chem final tomorrow and if it weren't for you i'd be failing
I am not fluent in English, but your explanations are so good so I always watch these instead of videos in my mother tongue!!
Bro this guy is actual the king of teaching chemistry
my textbook just defined acids, salts, bases and hydroxides in 3 lines -.- I'm so thankful for an explanation in which I actually get the information to identify them. Thank you!
Really Helped me during my last moments of revision
The way that this channel carries my biochem degree on its shoulders😥
You there only person who makes chemistry easy to me ,I wish you were my teacher ...I would collect distinction
Its 1:41am and I have a lab today. And i have pages of homework to finish. Thank you for saving my life.
finish as in firefighter water hose bumming out the siren goes back in forth everywhere
this guy never misses. thanks for saving my life

why would you need animation
to make it more fun
Thank you very much,🥰🥰 this video have just make me understand acid base equilibrium was so helpful and well explained 🙏🙏
My textbook is useless, so the videos are greatly appreciated.
i love the organic chemistry tutor who is basically god because knows everything that exists related to science on earth
