pH calculation for a polyprotic acid

7-6 This video describes how to calculate the pH for a general polyprotic acid, and carries out a numerical example for a 0.1 M solution of carbonic acid.

I have a final tomorrow and this greatly clears up titrations of polyprotic acids. I was always confused when to use Ka1 or Ka2 and you do a great job telling which one to use.

[ariamodir]

Helped me understand the material very well for my final tomorrow. Thank you.

[malshakakodikara]

You're a great teacher. Thank you

[weeb_slayr_]

This was an amazingly helpful and clear video. Thank you!

[adelinepangilinan]

very helpful. fyi is the ka1 written incorrectly?

[MariaFernanda-yvtw]

Thank you very much! Such a great explanation!

[Noobskism]

Great Video, this helped me a lot! Thanks!

when writing a diprotic acid reaction of sulfuric acid, H2SO4 + H2O --> SO4 + H3O, there's a missing hydrogen on the product side, so how do you write the correct equation?

[nucleophile]

Why you do t change H2CO3 conc. after HCO3- disociated, why it's not [H2CO3]=0, 1-2, 1*10^-4 - y

[hamedbarzinmehr]

This method of yours may be useful. But one should keep in mind that equilibrium concentrations never change . In the second equation the equilibrium concentration of hydronium is greater than that in the first and that's wrong . The true way of solving this problem is by writing proton balance and mass balance equations and then use approximations

hello how can i reach you please? i need an analytical chem tutor

[AveshShetty]

The Answer is INCORRECT because:-
Ka1 is incorrectly written as concentration of HCO3- is not x but x-y.
