A chemist titrates 170.0mL of a 0.2177M aniline C6H5NH2 solution with 0.7586M HBr solution at 25°C . Calculate the pH at equivalence. The pKb of aniline is 4.87 . 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 HBr solution added.
