Consider the titration of a 25.0 mL sample of 0.110M HC2H3O2 with 0.120 M NaOH. Determine each of the following.
1) Initial pH?
2) Volume of added base required to reach the equivalence point?
3) the pH at 4.00mL of added base?
4) the pH at one half of the equivalence point?
5) the pH at the equivalence point?
