HC2H3O2(aq) + H20(l) <=> H3O+(aq) + C2H3O2 (aq)

In aqueous solution, acetic acid as represented above. In 0.0105M HC2H3O2 (aq) at 25C, the hydronium ion concentration is 4.35 *10 -4 M. In answering the following, assume that the temperature is constant at 25C and that volumes are additive.

a) In an experiment a 20.0mL sample of 0.0105M HC2H302 (aq) was placed in a flask and titrated to the equivalence point and beyond using 0.0075M NaOH (aq).

i) Determine the volume of 0.0075M NaOH (aq) that was added to reach the equivalence point.
ii) Determine the pH of the solution halfway to the equivalence point.
iii) Determine the pH of the solution in the flask at the equivalence point.
iv) Determine the pH of the solution in the flask after a total of 30.0 mL of 0.0075M NaOH (aq) was added.
