Do not give handwriting solution.

A beaker with 2.00x10² 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 4.90 mL of a 0.490 M HCl solution to the
beaker. How much will the pH change? The pKa of acetic
acid is 4.740.
Express your answer numerically to two decimal
places. Use a minus ( ) sign if the pH has
decreased.
