Preparation of Buffer Solution and Measurement of pH

Web19 de jun. de 2024 · The ability of a buffer solution to resist large changes in pH has a great many chemical applications, but perhaps the most obvious examples of buffer action are to be found in living matter. If the pH of human blood, for instance, gets outside the range 7.2 to 7.6, the results are usually fatal. WebDetermining the pH of a buffer solution using the Henderson-Hasselback equation. In a buffer solution- [HA] = [A-], causing the log ( [A-]/ [HA]) --> log (1) = 0. From here, the Henderson-Hasselback equation becomes pH= pKa. In a buffer, with equal concentrations of acid and base, the pH = pKa. If given different acid and base concentrations,
