5) In order to determine the Kb of an unknown weak base, you decide to perform a titration. You accurately measure out 175.0 mg of the base, and dissolve it in a total solution volume of 25.0 mL. After that, you titrant the solution with 0.150 M HBr, and get the data shown in the table below. From this information, answer the following questions. Volume of HBr pH 0 mL a. Construct a fully labeled titration curve. 11.96 b. Determine the Kb of the weak base. 13.0 mL 10.75 c. Determine the molar mass of the weak 26.0 mL base. 30.0 mL 5.90 1.96
