Which of the following titration curves expresses the titration of a weak acid with a strong base?

You have an analyte solution of 50 mL of 0.2 M acetic acid (pK_a = 4.8). What volume of 0.05 M NaOH titrant needs to be added to get the final pH = pK_a?

Use the titration curve below. 

What is the predominate species in the solution of phosphoric acid at pH = 5?

Titration confirms an acetic acid solution to be 0.1 M. Calculate the pH. (acetic acid K _a = 1.76 x 10^-5 M).
