In Activity 2, there were 2 mL of buffer per well. Calculate the final pH of the undiluted buffer after 0.25 mL of 0.1 M NaOH is added. The K_a of CH₃COOH = 8 × 10^-5. Use the CH₃COOH buffer concentration calculated in Data Table 2, a balanced CH₃COOH + NaOH reaction equation, an ICE table, and a balanced dissociation equilibrium equation to help determine the pH.
