How do you exceed buffer capacity

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⁻ *(1)* pH = pKₐ + log([CO₃²⁻]/[HCO₃⁻]) = pKₐ + log(0.50/0.35) = pKₐ + 0.155 WebJul 27, 2024 · By doubling the total molar concentration of the buffer system will double the capacity of buffer at a given pH. Buffer can also be increased by using equimolar concentrations of the acid (HA) and its conjugate base (A – ). The buffer has its greatest capacity, when ratio [salt]/ [acid] are equal to 1, i.e. [HA] = [A – ].
