Part A A beaker with 1.30×102 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 5.20 mL of a 0.450 M HCI solution to the beaker. How much will the pH change? The PK, of acetic acid is 4.740. Express your answer numerically to two decimal places. Use a minus() sign if the pH has decreased.
