a. Calculate the pH of a buffered solution that is 0.100 M in C 6 H 5

Question:

a. Calculate the pH of a buffered solution that is 0.100 M in C₆H₅CO₂H (benzoic acid, K_a = 6.4 × 10^-5) and 0.100 M in C₆H₅CO₂Na.

b. Calculate the pH after 20.0% (by moles) of the benzoic acid is converted to benzoate anion by addition of a strong base. Use the dissociation equilibrium

to calculate the pH.

c. Do the same as in part b, but use the following equilibrium to calculate the pH:

d. Do your answers in parts b and c agree? Explain.
