WebbTheir optimal buffering capacity, or range, is defined by the dissociation constant, or ka, of the acid. We commonly discuss buffering capacity in terms of the pKa or the logarithmic constant of ka. We consider the buffering capacity of a specific buffer to be the pKa ± 1. For example, a buffer with a pH of 6.8 has a pH buffering range of 5.8-7.8.
