A buffer that contains 1.10 M base, B, and 0.700 M of its conjugate acid, BH, has a pH of 9.300. What is the pH after 0.0055 mol of HCl is added to 0.500 L of this solution? pH =

pH = pKa + log [B / BH+]

9.300 = pKa + log (1.10 / 0.70 )

pKa = 9.10

molarity of HCl = 0.0055 / 0.50 = 0.011 M = C

pH = pKa + log [B - C / BH+ + C]

pH = 9.10 + log (1.10 -0.011 / 0.7 + 0.011)

pH = 9.28
