pH Titration: Problem Set#1 Question #5

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 and the conjugate base.
Enter a volume of NaOH:
1.0 M NaOH = ml
For the above volume of NaOH, Calculate the pH
pH =
Use the steps described on Topic #1: pH Titration to solve this problem.
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.
