I've been searching the internet like crazy because I couldn't find a good explanation for polyprotic acid titration. This was so clear I feel like I could cry right now. Thank you sooo much!!!
A great explanation of why the pH at the equivalence point of a weak acid is >7 ! A subtle nuance that definitely helps on the AAMC practice questions.
In this case, you could use the Henderson Hasselbach equation to calculate pH. Since you can identify the pKa from the buffered regions on the graph, you can use pH = pKa + log (A-/HA)
At the half equivalence point pH=pKa. Ka=10^(-pKa) When half the acid is deprotonated you have [A-]=[HA]. This allows us to simplify the Henderson Hasselbach equation from pH=pKa + log([A-]/[HA]) to simply pH=pKa.
I feel like I owe this man coffee, thank you!!!!! :) One of my favorite MCAT prep channels!
You're very welcome!
i can get u a coffee, lol
I feel like I owe him my life.
Wow the best teacher ever, wow. You are such a gifted teacher! Thank you so much for your clear explanations.
Wow, thank you!

Simply the best MCAT channel

Please continue making more videos if you can :) I personally find them better than khan academy
This video just saved me, right before my biochem exam. Thank you!
Glad it helped! Thank you! Please share this channel with your peers!
first comment I post under a YT video, just to thank you soooo much, finally a good video for acid base titration
You're an amazing teacher
Thanks a lot❤❤
You shouldn't have stopped making Vids😔
This is great, a very clear and understandable explanation
Really Really helpful to clear all concepts related to Acid Base titration .Thanks a lot!!! :)
Wish I found this channel sooner!
In the special H2SO4 graph, does the first EQ point = pH b/c it's a still strong acid? Or does that rule not apply anymore?
You can usually use the pKa/Ka value of the first deprotonation to calculate the pH of a polyprotic acid.
Can you please send a lesson on how to get the pH of the mixture of an acid and a base. Thank you for the good explanation of filtration graphs

charming method simple and easy god bless
Glad you found it helpful!
Very informative. Nice and succint!!
Thanks!
are there no buffer videos?
thank you !!!!!
Very clear thanks Sir!!
Thank you!
so helpful!
Awesome!
Nice thanks sir
You're welcome :)
AMAZING
THANKS!
Thnx fam
We got you fam 😎
I dedicate this vine to you: I love you bitch. I ain't never gonna stop lovin' you, bitch.
Thank you very much. :)
You're most welcome!
Omg that was like me being in Chem haven!
Thank you! Please tell your peers about our channel :)
but u did not mention how to find out the pka ......
At the half equivalence point pH=pKa. Ka=10^(-pKa)
When half the acid is deprotonated you have [A-]=[HA]. This allows us to simplify the Henderson Hasselbach equation from pH=pKa + log([A-]/[HA]) to simply pH=pKa.
Sorry its titration graphs
