We’re being asked to calculate the volume of 0.1900 M NaOH required to titrate 0.0899 g acetic acid (HC2H3O2) to the equivalence point.
The reaction between HC2H3O2 and NaOH will be a double displacement reaction where H+ reacts with OH– and C2H3O2– reacts with Na+.
The overall reaction is:
HC2H3O2 + NaOH → H2O + NaC2H3O2
Recall that at the equivalence point of a titration:
