WebHowever it's unnecessary to calculate the pH of strong acid solution using the Henderson-Hasselbalch equation since we can do so using stoichiometry of H+ and assume that strong acids dissociate ~100%. So it's possible to use the Henderson-Hasselbalch equation, but it creates unneeded work when simpler methods are possible. Hope that helps.

We've neutralized half of the acids, right, and half of the acid remains. And using Henderson Hasselbalch to approximate the pH, we can see that the pH is equal to the pKa at this point. So let's go back up here to our titration curve and find that. Alright, so the pH is 4.74.

WebMay 17, 2024 · It is due to the fact that at half equivalence point, the pH of the solution is equal to the pKa value of the weak acid. And this pH does not depend on the initial concentration of the acid. You should take into account something that does not appear on your diagrams. The concentration of the strong base (used on the abscissa) is not given !
