WebMar 15, 2024 · Recall that the pH of a buffer solution is given by the Henderson-Hasselbach approximation: pH = pKa + log[A −] [HA] Because [HA] = [A −], the pH of this buffer solution equals the value of pK a for the unknown acid. Thus we can use the measured pH of this buffer solution to determine the value of pK a for our unknown acid. OPTIONAL fetch bedding sophie allport
