Consider a titration where 0.250 M NaOH is added to 50.0 mL of 0.400 M HC2H3O2.

1. How many moles of HC2H3O2 are in the original 50.0 mL sample? mol

2. Calculate the volume of NaOH required to reach the equivalence point when 0.250 M NaOH is added to 50.0 mL of 0.400 M HC2H3O2. mL

3. What volume of 0.250 M NaOH is required to react with exactly one half of the moles of HC2H3O2?

mL

4. Calculate [H+] concentration when exactly half of the HC2H3O2 has been neutralized by the NaOH.

[H+] = M

5. What is interesting about the concentration of [H+] in Q4?

6. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

7. If there is one question you would like to have answered in lecture, what would that question be?
