Problem 2

A friend asks the following: Consider a buffered solution made up of the weak acid HA and its salt NaA. If a strong base like NaOH is added, the HA reacts with the to form . Thus the amount of acid (HA) is decreased, and the amount of base (A_) is increased. Analogously, adding HCl to the buffered solution forms more of the acid (HA) by reacting with the base (A_). Thus how can we claim that a buffered solution resists changes in the pH of the solution? How would you explain buffering to this friend?
