Titrations of polyprotic acids | Acids and bases | AP Chemistry | Khan Academy

Titrating a polyprotic acid with a strong base produces a pH curve with as many equivalence points as there are acidic protons on the acid. The pKₐ values for these protons can be estimated from the corresponding half-equivalence points on the curve, where pH = pKₐ.

Thank you for the simple and concise explanation of these titration curves. You break it down perfectly!

[@refreshtwice3630]

First and love all your videos they all help with everything I haven’t had a problem that your videos don’t help me

[@sciencenerd7639]

I ❤️ Khan academy
Thanks so much, keep up the good work

I like the systematic approach, but I’m worried this is giving an overly simplistic view of polyprotic acids, there must be a consideration of strong/weak acid and this idea while isn’t required for a titration shouldn’t be neglected :/

[@danys9085]

thank you very much

[@hoh1113]

Very clear explanation, thanks 🤍🤍

Hello. I am here from russian version of this channel. I want ask you, what program do you use for your videos? You drow with a computer mouse or with a Graphics tablet?
I hope you understand my bad-english comment and you will answer me)

На самом деле в вашем комментарии всего одна ошибка: рисовать пишется ''draw''. Надеюсь вам ответят.

but why the ph of HA is 7 since it is an acid?

[@rekha_yt_2115]

Sir I have a doubt in Math can u help me please
