WitrynaThe 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. painting face ideasWitrynaA buffer is an aqueous solution made up of a weak acid and its salt (acid buffer) or a weak base and its salt (base buffer) (basic buffer). When a tiny amount of strong acid or base is given to it, its pH varies very little, and it is thus used to keep a solution’s pH stable.
