q 1 : What effect does a higher concentration of sodium acetate have on the pH of solution after the acetic acid has been
added? Propose an explanation based on your understanding of Le Chatelier’s Principle.
q: 2 Do the pH values of the various samples change after 15 minutes and/or 60 minutes? Why or why not?
q: 3 If you repeated this experiment, substituting sodium chloride for sodium acetate and concentrated hydrochloric acid
for acetic acid, would you expect the pH changes in different concentrations of sodium chloride solution to be greater than
or less than the corresponding changes in the sodium acetate solution. Why?
