A ‘pH buffer‘ is a solution of a weak acid/base and its conjugate base/acid, which resists a change in pH and is prepared via the following steps: 1. Choosing the desired buffer system by comparing the pK value(s) for the weak acid/base and the target buffering pH(s) (= pK(s) ± 1, range (s) of maximal buffer capacity 2. Determining the total desired buffer concentration, based on the desired buffer capacity and ionic strength 3. Preparing stock solutions of the buffer…
