i love you so much chad! i don't know how you get this much motivation to teach such a complex subject with this ease! greatest chemistry teacher of all time
Thanks Divital! And I hope I'm still getting better every day. But I also know who I consider the greatest chemistry teacher of all time and I am definitely not at his level. Unfortunately, he is not on youtube, but Dr. George Wolf teaches quantum mechanics like nobody else!👍
you have made my chem lecture slides even more useless than they were thank you so much for all your videos. if i knew where u lived i would buy u chocolate & wine and a newtons cradle or something idk but ur the best dude
Basically spent my whole spring beak with you. These videos are extremely helpful! I used to dread doing chem but learning chem from you makes it exciting to solve problems, thank you so much!! If you could, can you pleasee go over titration(curve) of polyprotic acids?
10:07 if the indicator is a weak acid as it also gets titrated with a strong base shouldn't it make a buffer, even for a small period of time ? (By the way in chatgpt and deepseek says it doesn't get titrated, also from searching youtube on how indicator works couldn't find similar approach, honestly to me it makes sense that it is indeed being titrated, but i can't understand it fully) So we're gonna have phenolphthalein, a weak acid and a NaOH a strong base, as the NaOH reacts with the weak acid and creates a salt(that contains the non-negligible conjugate base of phenolphthalein) at some point even for a small period of time the concentrations of the phenolphthalein and its conjugate base are gonna be close to 1:1 ratio and even exactly 1:1 Wouldn't that be a problem?
Around 23:00, you say that the moles of Acid and Conjugate Base are equal, but is it more accurate to say that the Molarity of the Acid and its Conjugate base are equal at the equivalence point? Is it true that at the half equivalence point, the concentration and moles of Acid and Conjugate base are equal? Or can the concentration of the Acid and Base be different from the moles of Acid and Conjugate Base? I hope my questions make sense.
I mean you can approach it either way since we are dealing with the same volume, Since there is no change in volume the moles won't be altered unless we will get a different value for the molarity. I hope it helps
Thank you so much, this is extremely helpful. Quick question, at the half-equivalence point of each of the last two titration curves, is the region of plus or minus 1 around this point the buffering region?
Hello Divital! There is definitely some editing that goes on behind the scenes and every once in a while I am unhappy with a video after editing it and will go and refilm the whole thing (it happened with this lesson, but it's the first one in this whole playlist). Glad you found it helpful!
sir, i understand why pka is equal to ph in the 1/2 titration point. but we can not say the same to poh and pkb in the equivalent point right? after all it depends on the concentration, or did i just miss understand your explaination?
Im kinda stuck with the Equivalance point part. On the graph, it shows you have to ad 20mL of NaOH. But when you were describing the 1/2 equivalnce point, in the initial equation you wrote 10 mol HF+ 10 mol NaOH. Can you clarify that part?
Sir when we are performing titration of strong acid with a strong base.....light pink color indicates equivalence point or end point ?? As phenolphthalein gives pink color in basic medium and colorless in acidic medium .....so light pink color would be in neutral medium ?
Hey! Phenolphthalein noticeably changes colour between pH 8-10 so this is slightly past the equivalence point. It would be light pink from about 8.3-9 pH

For my gen chem 1 online class The professor would read stuff from the textbook and the audio he posted were horrible quality Like clockwork i watched the first half of this series and alhamdulilah i got a 90 on my final and A overall Thank you prof chad 🫡

Hi Possible to provide his website address? I will look into his profile and listen to his talks if possible.

Thanks, Jakobson - glad the videos are helpful!
this comment is so real
@@penelopebeekman9826 yessss because the channel is real
a real cheat code
AMAZING video for final exam review, props to you man!!!
You made the explanation so clear!!!! Really helped me understand acid base titrations :))
Excellent - glad to hear it!
Just wanted to thank you. I wanted to review this part of solution chemistry and you nailed it.
You're welcome!
Excellent lecture Chad - so easy to understand. You are an awesome teacher.
Glad it was helpful!

Lmao me 2! Also got the same request.
This is going to help so many students
Glad to hear it Dom :)
Your videos are great and I really admire the way you make science coherent. Also, I love your shirt!
Thanks x3 - Happy Studying!
Chad you''re amazing! best teacher ever!
Thank you very much!
wow i really love ur videos, it gets down to the small details. love it
Glad you do!
about to have my final exam for gen II chem, I'll let you know if I cooked or got cooked
Thank you so much ❤️💕 I enjoyed this lecture..
You are very welcome, harry!
Thanks, very patiently and thoroughly explained.
You're welcome!

Thank you for this! Do you by any chance have a video for the titration of polyprotic acids and bases, please?
You are welcome and check the last chapter (15:20 onwards) of this one: ua-cam.com/video/kSfs0WenLXo/v-deo.html
Nice sir. Good night I will watch on tomorrow morning.
Excellent - hope you enjoy!
by the way do you ever revise stuff before ? this was just flawless...
