Question

For a 0.00596 M solution of sodium benzoate, NaC₆H₅CO₂, do the following.

Identify the major species (other than water) that has no effect on pH. Include charge (if any) and phase in parentheses.

Balance the equilibrium reaction for the major species that does have an effect on pH. All species should include charge (if any) and phase. On the product side, list the cation (if any) first, followed by the neutral molecule (if any), and the anion (if any).

Compute the pH of the solution. K_a of HC₆H₅CO₂ is 6.3E-5.
