WebJan 30, 2024 · When the desired pH of a buffer solution is near the pK a of the conjugate acid being used (i.e., when the amounts of conjugate acid and conjugate base in solution are within about a factor of 10 of each other), the Henderson-Hasselbalch equation can be applied as a simple approximation of the solution pH, as we will see in the next section. WebpH = pKa + log10 ( [A–]/ [HA]) Where [A –] denotes the molar concentration of the conjugate base (of the acid) and [HA] denotes the molar concentration of the weak acid. Therefore, the Henderson-Hasselbalch equation can also be written as: An equation that could calculate the pH value of a given buffer solution was first derived by the ...
