Based on your titration curves, determine the amount of sodium hydroxide added at the equivalence point in steps 3, 5, and 8. Use this information to calculate the total moles of acid that were neutralized in each of the titrations.
26.0mL NaOH, 0.5 M HCl 0.5M NaOH
1.0mL NaOH, 0.5 M CH3CO2H 0.5M NaOH
50.0mL NaOH, 1.0 M CH3CO2H 0.5M NaOH
HCl + NaOH -> H2O + NaCl
CH3CO2H + NaOH -> NaC2H3O2 + H2O

The half‑equivalence point of a titration occurs half way to the
equivalence point, where half of the analyze has reacted to form
its conjugate, and the other half still remains unreacted.
