Answer Questions #27 through #31 about the titration curves below (labeled a and b) for two differentbases. The titrant acid used in both cases was 0.100M HCI and the volume of the base solutions in bothcases was 75.0 mL mL.14141212 -1010-8-8-6-6-4-4-2-2-0-2040608010020406080100(a)Volume of acid added (mL)Volume of acid added (mL)(b)27. In both of these titrations, what are you titrating with the HCl solution?A) Both are strong bases.B) Both are weak bases.C) Base in (a) is strong; base in (b) is weak.D) Base in (a) is weak; base in (b) is strong.28. Which of the two titrations has a base solution that is more concentrated?A) (a)B) (b)C) Both (a) and (b) are the same concentrationD) It is impossible to say without knowing the exact K, values of the two bases.E) Titrating with HCl won't work. You need to use another acid in the titration.29. Which titration has the stronger base (larger K value)? Be careful: Make sure you compare the Kh values ofthe bases, not the Ka values of the conjugate acids. Also, don't forget the relationship between Kb and pKb.A) (a)Hdна 28.

You need to use another acid in the titration.30. Could the base titrated in (b) be used as part of a buffer? If so, what pH could be maintained by this buffer?A) Yes, pH = 10B) Yes, pH = 8C) Yes, pH = 5D) NoE) It is impossible to say because the titration curve is for a strong base.31. Choose an indicator from the table on p. 817 of your textbook that would be suitable to signal theequivalence point of titration (b).A) crystal violetB) bromphenol blueC) phenol redD) phenolphthaleinE) alizarin yellow R
