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:
