Chapter 14, Problem 123E

With group members acting as atoms or ions, act out the reaction that occurs when HCl is added to a buffer solution composed of ${\text{HC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ and ${\text{NaC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$. Write a script for a narrator to describe the processes that occur, including how the buffer keeps the pH approximately the same, even though a strong acid is added.
