Web17 ian. 2024 · Let's start with the acid dissociation constant (Ka): pKa of a carbonate buffer equals 6.4. Let's assume that both the acid's and conjugated base's concentrations are equal to 6 M. Utilize the equation: pH = pKa + log ( [A⁻]/ [HA]) pH = 6.4 + log (6 M/6 M) pH = 6.4 + log (1) pH = 6.4 + 0 pH = 6.4 The pH of our buffer is equal to 6.4.
