WebJan 30, 2024 · Howto: Solving for Ka. When given the pH value of a solution, solving for Ka requires the following steps: Set up an ICE table for the chemical reaction. Solve for the concentration of H 3O + using the equation for pH: [H3O +] = 10 − pH. Use the concentration of H 3O + to solve for the concentrations of the other products and reactants. 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⁻
