(Answered) A chemist titrates 2000ml of a 05495m pyridine c5h5n

Academics

A chemist titrates 200.0mL of a 0.5495M pyridine C5H5N solution with 0.0872M HBr solution at 25°C . Calculate the pH at equivalence. The pKb of pyridine is 8.77. Round your answer to 2 decimals places.you may assume the total volume of the solution equals the initial volume plus the volume of HBr solution added.
