You have 500.0 mL of a buffer solution containing 0.30 M acetic acid (CH₃COOH)and 0.20 M sodium acetate (CH₃COONa). What will the pH of this solution be after the addition of 20.0 mL of 1.00 M HCl solution? [K_a = 1.8 × 10^-5]Hint: Adding HCl will change the amounts of both the acid and the base. Calculate the pH based on the new amounts.
