Consider Titration of 25 mL of .1 M CH3CO2H With .1 M NaOH. Calculate The pH After Adding The Following Volumes of NaOH: a. 0 mL b. 12.5 mL c. 20 mL d. 25 mL e. 37.5 mL I do know the correct answers, I just don't how to get to the answers. a. pH = 2.87 b. pH = 4.74 c. pH = 5.34 d. pH = 8.72 e. pOH = -log (0.0192 M) = 1.72  14 - 1.72 = 12.28 (I been having a hard time people getting the correct answer for part e, people keep getting 12.30 as the answer, but it is not. The correct answer is 12.28. I only remember how to do the last steps to get part e answer, which is 12.28, as it can be seen).

Question

Consider Titration of 25 mL of .1 M CH3CO2H With .1 M NaOH. Calculate The pH After Adding The Following Volumes of NaOH:

a. 0 mL

b. 12.5 mL

c. 20 mL

d. 25 mL

e. 37.5 mL

I do know the correct answers, I just don't how to get to the answers.

a. pH = 2.87

b. pH = 4.74

c. pH = 5.34

d. pH = 8.72

e. pOH = -log (0.0192 M) = 1.72 

14 - 1.72 = 12.28 (I been having a hard time people getting the correct answer for part e, people keep getting 12.30 as the answer, but it is not. The correct answer is 12.28. I only remember how to do the last steps to get part e answer, which is 12.28, as it can be seen).
