WebAug 4, 2016 · We can solve for the pKa by subtracting the given pKb from 14: 14 −4.75 = 9.25 Thus, your pKa is 9.25 Next, we can obtain the [base] and [acid] from the question. [N H 3]= .50 M [N H 4] =.20 M We're not really concerned with the chloride anion that attached to the ammonium ion because it's a spectator ion and it has no effect on the buffer system. WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that.
