WebbBuffer capacity falls to 33% of the maximum value at pH = p Ka ± 1, to 10% at pH = p Ka ± 1.5 and to 1% at pH = p Ka ± 2. For this reason the most useful range is approximately p Ka ± 1. When choosing a buffer for use at a specific pH, it should have a p Ka value as close as possible to that pH.
