WebMar 31, 2014 · The Henderson-Hasselbalch equation is: pH = pKa +log( [A−] [HA)) Substituting, 3.21 = 2.15+ log( [A−] [HA]) Solving, log( [A−] [HA]) = 3.21–2.15 = 1.06 [A−] [HA] = 101.06 = 11.5, or [A−] = 11.5[HA]. Since the original concentration was 2.37 mol/L,some re-formatting plus a: [A−] + [HA] = 2.37 mol/L. Substituting, WebSo the Henderson-Hasselbalch equation just says that the pH is equal to the pK_a plus the log of A minus over HA, where HA is our weak acid and A minus is its conjugate base. And as you can see up here, an acid and its conjugate base are just related by the fact that the acid has an extra H. We can rearrange the Henderson-Hasselbalch equation ...
