Chemistry buffer solution

WebThe 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 WebNov 28, 2024 · Solve this problem by plugging the values into the Henderson-Hasselbalch equation for a weak acid and its conjugate base . pH = pK a + log ( [A - ]/ [HA]) pH = pK a + log ( [C 2 H 3 O 2-] / [HC 2 H 3 …
