A chemist titrates 90.0 mL of a 0.1325 M dimethylamine ((CH3)2NH) solution with 0.5618 M HBr solution at 25c. Calculate the pH at equivalence. The pKb of nitrous acid is 3.27. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of solution added.
