(Use this to answer Qs 13-14.) Trinity decides to perform two titrations:(one with 20.0 mL of 0.500 M 2 NH3 and one with 20.0 mL of 0.500M KOH. Both are titrated with 0.350 M HBr. 13) Is the pH at equivalence point for each titration acid, basic, or neutral? a. Both are acidic. b. Both are basic. e. NH3 is basic and KOH is neutral. ab. NH3 is neutral and KOH is acidic. c. Both are neutral. d. NH3 is acidic and KOH is neutral. ac. NH3 is neutral and KOH is basic. 14) On the same graph, sketch the titration curves for both scenarios listed above. Provide the sketch in the blank space below. Your titration curve for NH3 will be a normal line while your titration curve for KOH will be a dotted line.
