Define a buffer in chemistry
WebIt depends on what you mean by "a significant change". The buffer capacity is defined as the amount of acid or base you can add without changing the pH by more than 1 pH unit. I will define "significant change" as 1 pH unit. The equation is HCO₃⁻ + H₂O ⇌ H₃O⁺ + CO₃²⁻ 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.
