(b) Give the approximate pH at the equivalence point for the titration of each acid.

(c) Explain why the pH at the equivalence point differs for each acid.

(d) Explain why the starting pH values of the two acids differ.

(e) Which indicator could be used for the titration of Acid 1 and for the titration of Acid 2? Explain your choices.
