35PRACTICE PROBLEM
A chemist conducts a reaction that produces protons buffered at pH = 9.8. Determine if it is better to use a protonated triethylamine/triethylamine buffer (pKa of protonated triethylamine = 10.8) or would be better to use an ammonium/ammonia buffer (pKa of ammonium = 9.3) instead.
