Nov 28, 2022 · Learn how to calculate the pH of a buffer solution or the concentration of the acid and base using the Henderson-Hasselbalch equation. See a worked example with a weak acid and its conjugate base.
One way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution.
