WebA 1M solution of acetic acid for example only has a percent ionization of 0.42%, meaning only 0.42% of the acetic molecules turn into acetate. ... So a more general definition for a buffer solution could be a weak conjugate acid-base pair. We can calculate the pH of the buffer solution that forms when we mix the two solutions together using the ... 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.
