A beaker with 1.40×102mL 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 7.10mL of a 0.410\it M \rm HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.
