Part A
A beaker with 1.00x102 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 7.00 mL of a 0.430 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.
