A 500.0 mL buffer solution is 0.10 M in benzoic acid and 0.10 M in sodium benzoate and has an initial pH of 4.19. What is the pH of the buffer upon addition of 0.020 mol of NaOH?
when we add NaOH it will react with benzoic acid and form the sodium benzoate which increases the concentration of sodium benzoate
