Academics

A beaker with 1.50×102mL 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 7.20mL of a 0.330\it M \rm HCl solution to the beaker. How much will the pH change? The {\rm p}K_{\rm a} of acetic acid is 4.760.
