WebOne 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 … WebThe pH range of a buffered solution is given by the Henderson- Hasselbalch equation. For the purpose of the derivation, we will imagine a buffer composed of an acid, HA, and its conjugate base, A -. We know that the acid dissociation constant p Ka of the acid is given by this expression: The equation can be rearranged as follows:
WebThe limitations of the Henderson-Hasselbalch equation: The Henderson-Hasselbalch equation does not account for water’s self-dissociation; it cannot provide the correct pH … WebHenderson-Hasselbalch Equation As discussed earlier, it is customary to express the H + concentration in pH units rather than in actual concentrations. Recall that pH = −log H +. …
