pH Titration: Problem Set#1 Question #4
- You are given 200 mL of an acid of unknown concentration.
You have a 1.0 M NaOH solution to use in a titration experiment.
- a) Determine the pKa and concentration of the acid.
- b) Submit your graph of pH vs. equivalents of NaOH.
- c) Identify the acid from the list in Campbell, Table 2.6.
- d) Draw the chemical structures of the acid (HA) and the conjugate base (A-).

Use the steps described on Topic #1: pH Titration to solve this problem.
You should plot at least four points above and four points below the pKa of the acid.
Note: In contrast to a "wet lab" titration where the pH would increase stepwise with each addition of NaOH, this titration uses a new solution of acid for each volume of NaOH added.
