Q12. Choose True or False regarding a buffer solution. 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. Buffering capacity increases as the molar concentration of the buffer salt/acid solution increases. Consists of a mixture of a strong acid and its conjugate base, or vice versa. Buffer solutions achieve their resistance to pH change because of the presence of an equilibrium between the weak acid HA and its conjugate base A- [Choose ] [Choose ] [Choose] [Choose ] [Choose] >
