WebAlkaline buffer solutions are commonly made from a weak base and one of its salts. A frequently used example is a mixture of ammonia solution and ammonium chloride solution. If these were mixed in equal molar proportions, the solution would have a pH of 9.25. Again, it doesn't matter what concentrations you choose as long as they are the same. 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. [1]

How to Calculate the pH of a Buffer Chemistry Study.com

WebOne way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution. When [HA] = [A⁻], the solution pH is equal to the pKₐ of the acid. Created by Jay.
