Agenda 4-5-12

AP Chemistry

We practice some more pH buffer problems involving titration curves. Here is another practice problem:

20.00 mL of 0.160 M HC₂H₃O₂ (K_a=1.8x10^-5) is titrated with 0.200 M NaOH.

1. What is the pH of the solution before the titration begins?
2. What is the pH after 8.00 mL of NaOH has been added?
3. What is the pH at the equivalence point?
4. What is the pH after 20.00 mL of NaOH has been added?
