Question
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).
Answers
pH = pKa + log(base)/(acid)
Plug in pH you want, plug in pKa for NH3 (that will be Kw/Kb since you can't find the Ka listed in any table), you're given NH3 (make up a volume for that and enter moles), solve for (NH4Cl). Convert to grams in the volume you chose for the NH3.
