What is the Henderson-Hasselbach equation? Use the equation to determine the ratio of [A-] to [HA] necessary to create an ammonium chloride/ammonia buffer with a pH of 8.50. Describe how to make this buffer given a solution of 0.1 M NH3 (aq) and a bottle of NH4Cl(s).
Why can a buffer be created by the addition of sodium hydroxide to acetic acid, but not from the addition of sodium hydroxide to hydrochloric acid?
