Question

Original concentration of Acetic Acid was 0.1033 M and NaOH was 0.1104 M, not sure if I filled out the chart correctly and how to get the equillibrium concentration

B. Calculate the pH after 17.50 mL of NaOH is added to 35.00 mL of acetic acid using the concentration
assigned in Beyond Labz:
• First assume the acid-base neutralization reaction is irreversible and goes to completion:
HC;H;O2 (aq)

+ C¿H3O2 (aq)
Moles before reaction 0.0036
0.0019
Change in moles -0.0019

+0.0019
Moles remaining after reaction 0.0017
