A beaker with 125 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 0.360 M HCl solution to the beaker. How much will the pH
change? The pKa of acetic acid is 4.740.

A beaker with 125 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 7.00 mLof a
0.360 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.

A beaker with 130 mL of an acetic acid buffer with a pH of 5.00
is sitting on a benchtop. The total molarity of acid and conjugate
base in this buffer is 0.100 M. A student adds 6.20 mL of a 0.490 M
HCl solution to the beaker. How much will the pH change? The pKa of
acetic acid is 4.760.
Express answer numerically to two decimal places. Use a minus
(-) sign if the pH has decreased.
