What affects buffer capacity?
What determines "buffering capacity"? Buffering capacity refers to the amount of added acid or added base that can be neutralized by a buffer. It is determined by the concentrations of the conjugate acid and conjugate base. Buffering capacity increases as these concentrations increase.
What are the two factors that affect buffer capacity?
While the ratio of [A-]/[HA] influences the pH of a solution, the actual concentrations of A- and HA influence the effectiveness of a buffer. The more A- and HA molecules available, the less of an effect addition of a strong acid or base will have on the pH of a system.
