A beaker with 1.40×102 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 mol L−1. A student adds 7.90 mL of a 0.470 mol L−1 HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.
Express your answer numerically to two decimal places. Use a minus ( − ) sign if the pH has decreased.

Question: A beaker with 1.40×102 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 6.60 mL of a 0.430 M
HClsolution to the beaker. How much will the pH change? The
pKa of acetic acid is 4.740.
