Calculate the final pH of the undiluted buffer after 0.25 mL (5 drops) of 0.1 M NaOH is added. Ka of CH3COOH is 1.8 × 10-5. Use the CH3COOH buffer concentration calculated in Table 2, an ICE table, and a balanced dissociation equilibrium equation to determine the pH. The undiluted buffer has a pH of 4.7 and has a 0.05 M concentration of sodium acetate (not sure if this detail is needed but thought I'd include).
