WebNov 21, 2014 · Using the standard concentration c ∘ we do not have to care about units. pH = − lg(c(HX +) c ∘) Now we can substitute in (4) and we will have a nice definition of the pH of a neutral solution. pH = − lg(√Kw c ∘) The second formulation includes a very crucial point. 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.
