Draw the experimental outcome for a titration analysis involving a titrant and titrand (the pH vs. volume titrant added response curve), wherein the titrand is the weak, monoprotic base aniline (0.05000 F, 0.10000 L), and the titrant is a strong monoprotic acid (0.1000 M) that has been standardized. Calculate what the pH is at 0 mL added strong acid, the quarter-, half-, and three-quarter-equivalence points, the equivalence point, and when excess acid has been added. For the last point, pick a volume roughly 5 mL past the equivalence volume and calculate the pH. What is the pH at 1 mL past the equivalence volume (you'll need to know about mass and charge balance to do this)?
