Webbuffer capacity: the amount of hydrogen ion (or hydroxyl ion) required to bring about a specific pH change in a specified volume of a buffer. See also: buffer value . WebStimulated saliva was collected and divided into two separate millimetric tubes to calculate the buffer capacity of the saliva, determine Streptococcus mutans and Lactobacilli levels and measure the pH of the saliva. A Caries Risk Test buffer strip was used to calculate the buffer capacity. WebBuffer 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.
