WebpH and Buffers Defined pH is a measure of the concentration of H + [H 3 O +] ions in a solution.Only the concentration of H + and OH-molecules determine the pH. When the concentration of H + and OH-ions are equal, the solution is said to be neutral. If there are more H + than OH-molecules the solution is acidic, and if there are more OH-than H + … 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, WebTypes of buffer solutions (a) Acidic Buffer: It is formed by the mixture of weak acid and its salt with a strong base.
