- 068 - Acid-Base Equilibrium
In this video Paul Andersen explains how acid-base chemistry can be understood in terms of equilibrium. Water is present in all acid-base chemistry and is amphoteric in nature. The Ka and Kb values can be used to determine the strength of an acid or a base. Titrations can be used to student neutralization reactions between strong and weak acids and bases.

Totally just learned more about Ka and Kb in that 10 minute long video than I did in a week of class
Its all fun and games until it the calculations kick in
Just for anyone who sees this in the future, it’s fake. Please do not use it. It will ask for money in order to get account details but something tells me you’ll never get that info and just waste your money.
Everyone listen to Scratchbull. Those first two replies to my comment are scammers. Don't trust stuff like this online.
@@scratchull report it I did
@Hamza Zafer it got deleted maybe lol
No kidding! 😂
Thank you so much for your video. You make chemistry not as daunting and scary as it may seem, I wish all chemistry teachers were as great as you. It brings me so much relief to actually understand what's being taught as you introduce the topics gradually and interestingly in your videos, instead of simply throwing definitions and problems at students. You remind me why I'm fascinated with chemistry, or just science in general, in the first place and that a deep knowledge of these subjects is indeed attainable.
Chem test tomorrow and I have no idea what I am doing, but this helped tremendously, thank you!!!!!!
i’m about to take a chemistry final and i’m so glad i watched this. when my professor explained this, i had ZERO idea what he was saying.
Bruh this was so helpful like foreal you the man for this, I'm supposed to learn chemistry from a computer but on the low I been learning everything through you.. Keep it one hunnid 💯
Why are you writing like that, it's not like anyone here is going to think that you're not cool for writing like a normal person.
+hjaltello shut up
This is chemistry man you must keep it within scientology terms. Don't want to send any cool kid signals to these nerds who expect bad boys like you to be unsuccessful in life. Holy saint Stephen Hawkin will not be pleased to know cool kids are infiltrating the protected realm of scientology. Religious people aren't allowed either shhhhhh
Skid Seems you had a hard time in life Skid. Did you stop taking your antipsychotics?
THE UNKNOWN Wait. what??? Should be the other way around in this conversation bro.
Your videos are amazing and so helpful. The pictures and diagrams you use really help me visualize what you are saying. Thank you so much and keep on making videos!
i love how your videos have practical and "why you should care" examples! awesome work
THANK YOU MR ANDERSON your videos are still being watched and helping people every day!!
Thank you for the lessons you've been teaching the whole time, i found this really helpful , WISH YOU THE BEST
You are the best online teacher that I have ever experienced!!!!!!
You clearly haven't watched Hank green on Crash Course Chemistry
Good teacher indeed
Thank you so much for the channel! It's my second semester doing chemistry, and your videos have been a tremendous help!!
Mr. Andersen, thank you from the bottom of my heart!!! You are doing the best job at one of the most important jobs in the world😏!!
I'm done with chemistry as a nursing major, but I watch your video to expand my knowledge. Great work!!!
It's rare to find a teacher that teaches like this. Thank you for your videos sir, they help thousands of students 🫡
please make more videos! maybe ones that are more on organic chemistry your videos helped me survive gen chem and now im in ochem having trouble with newmans projections :(
WOAHHHHHHHHHHH! Man just summarised my whole chemistry Module into 10 minutes, That's like a terms worth theory explained so succintly. Damm. This 101% helpful.
I love the way he speaks and it makes really easier to understand a topic like that, than in a 2hs class! Amazing.
A BIIIIG THANK YOUUU ! I had this lesson yesterday and i didn't even get 1% and this saved my life i really understand every thing thank you sooo sooo sooooo much ❤️❤️❤️❤️❤️😁😋✌️👌👍
You are the best teacher ever! Thanks for doing this!
I just wanted to thank you so so much for helping me in chemistry
I love the insightful videos! Why some teachers just cannot explain things!
THANK YOU SO MUCH!!!!!!!!!!!!!!! chemistry final this week and didn't really get it until this video.
Great video! It's very engaging and it can definitely help Chem students!
It's very helpful!
I appreciate your work
Thank you! Your videos are very helpful!!
It was helpful, Mr Anderson. Thank you so much x)
you are more helpful than my chemistry teacher
This video is great thanks-much clearer.
I'M YOUR FAN!! you are so helpful. Thank you so much!!
thank you so muchh!!! never understood this concept until now!😭
I have a chem test tommorrow and this was a good revision before sleep😅💜
Thank you soooo much! Feeling ready for the final exam :-)
Very helpful indeed, thanks!
Why does the concentration of water remain constant?
Amazing video! Thank you
That was helpful man thanks keep it up
Are Hydronium is temporary , unstable Molecule that omly exist in water when Mixed with acid and base ?
you are a LIFESAVER. thank. you. endlessly.
what type of program is used to write on in these videos? I would like to try and use the program.
Thanks for making me a better Chemist
How do you know whether a compound is donating a proton to another?
how can it be accepting or donating PROTONS?its electrons right?
I love you! Thanks for this!
Wow cleared so many doubts just in starting great
Respect, you are the best :D
Thankyou for the video!!!
can you please make a video of pka?
This is just simply awesome . Please make more videos and start a big foundation like Khan academy but only for pure science.
Thank you, profesor!
You are the MASTER
Thank you
great video!
very educative.thank you regards
How did he get the numbers for Ka
So, are you saying that the equilibrium of a strong acid and a strong base is a pH of 7 because 7 is neutral?
How do you get the kw= 1X10^-7 from the kw provided?
I feel like there is supposed to be an index to get these numbers to get the kw/ka. Also what are the differences between kw or ka.
its 1 to 1 ratio
kw = 10^-14 which equals [h3o+][oh-] and since its 1 to 1 then [10^7][10^7]
Thank you so helpful.
At 3:50 should be pOH=-log[OH-] ==> there is an additional PLUS sign [OH-+]
Thank you sir, your too good
This guy's the man.
"Seems like a confusing solution." I see what you did there ;')
where do you get the value of products over reactants? to find Ka?
you should be given an initial concentration, or a pH/pOH value and then use an ICE table to figure out the Ka. You can also divide the Kw by the k
Kb of the cojugate base to find the Ka. Sorry this is over a month due, but hopefully it'll help someone else!
How do you calculate the equations to get the answer in order to identify wether it's weak or strong?
Where does the Kw= 1*10^-14 come from? Is it just given?
Yeah, it is the constant for all acid-base equilibriums.
when you ignore its usually liquid and solid
Ohh, that was helpful, thank youu)
So useful!
While your video was helpful with explaining the concept, a lot is desired with explaining the formulas. You didn't explain where you got your numbers when doing the Products/Reactants equations, you just stated what it equaled and whether it was a strong or weak acid.
This was so helpyl
dear how can make thick HCL for toilet cleaner please guide me
I would die for this man
CO2 (g) + H2O (l) H2CO3 (aq)
Calculate the equilibrium constant using the following concentrations [H2CO3] = 7.75 x 10-4 M and [CO2] = 5.65 x 10-1 M
Very nice
thank you!
Thank you! :)
How do you find the ka value?
Depends on its acidic strenght, Ka = M/[H+] for finding the strong acid constant
Very helpful
Protons donates or electrons donates plz elaborate in acid
You had me all the way up until 6:37 then it went way over my head
Thanks boze
watched this during my first block gonna write the test second block hopefully imma get a 100!!
Thank you
500xs better than my professor!!!!!!!!!!!!!!!!!
didnt specify tempurature
25 Celsius I believe
Mr. Anderson: Hi, it’s Mr. Anderson
Me: MY FUCKING HOMIE MR. A, I love this man
thank you
I LOVE U BRO!
Got it. Proton = Hydrogen :)
Mhmmm
I still don't understand why you can just ignore the concentration of water in Kw
because water is the solvent and its concentration doesn'tchange
5:37 "Yeah, there's a cool youtube video that'll be helpful, but I'm not going to tell you. MWAHAHA!"
+Giovanni Vargas I would love to see it
czcams.com/video/onGDi1KKjdM/video.html
thank youuuuuu
much better than my professor
sexy. Plus it was super helpful. I never knew the significance of negative log
BY FAR THIS IS THE HARDEST ONE
Donating protons??
so much has gone over my head huh
I love you!
I don't take chem cuz we don't do that at my school but I always learn it cuz it's interesting to me
thank
