Abstract In this paper, the pH of several common weak acid HA and weak base B- mixed solutions were calculated, and their buffering capacity was analyzed. The results show that the HA-B- solution has a certain buffer capacity. When the KHA/KHB is close to 1, there are mainly two buffer pairs of HA-A- and HB-B-. When KHA/KHB is greater than 1 000, there is only HA-A- buffer pair.
