What is your problem with this bekah?
For a you must have worked a hundred of weak acids problems with a known starting molarity.
At first glance it looks like 2 is a buffer problem that can be solved with the Henderson-Hasselbalch equation.
enzoic acid is a weak monoprotic acid with Ka = 6.5×10-5 M. NaOH(s) was gradually added to 1.00 L of 8.66×10-2 M benzoic acid.
1. Calculate the pH of the solution before the addition of the base.
2. Calculate the pH of the solution after the addition of 5.20×10-2 mol of NaOH(s).
