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 ... WebSep 12, 2024 · To determine the pH of the buffer solution we use a typical equilibrium calculation (as illustrated in earlier Examples): Determine the direction of change. The equilibrium in a mixture of H 3 O +, , and CH 3 CO 2 H is: The equilibrium constant for CH 3 CO 2 H is not given, so we look it up in Table E1: Ka = 1.8 × 10 −5.
