What is the pH at each of the following points in the titration of 25.00 mL of 0.100 M CH₃COOH with 0.100 M NaOH?

(a) Before the addition of any NaOH (initial pH)

(b) After the addition of 10.00 mL 0.100 M NaOH (before equivalence point)

(c) After the addition of 12.50 mL 0.100 M NaOH (half-neutralization)

(d) After the addition of 25.00 mL 0.100 M NaOH (equivalence point)

(e) After the addition of 26.00 mL 0.100 M NaOH (beyond equivalence point).
