POST-LABORATORY QUESTIONS 1. Explain how it is possible for the concentration of acetic acid to be higher than that of hydrochloric acid in solutions that have the same H3O ion concentration (same pH)? Remember, both acids ionize to form only one mole of hydronium ions per mole of acid that ionizes. 2. Do you think it is accurate to consider the titration end point as the same as the "equivalence point"? Why? How do you know that an indicator's color...
