WebAug 3, 2024 · Buffer capacity is the measure of a buffer’s ability to resist pH change. A higher buffer concentration has a greater buffer capacity. This means that a greater … 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
