Question

A chemist titrates 90.0 mL of a 0.0895 M ethylamine (C₂H5NH₂) solution with 0.8961 M HCl solution at 25 °C. Calculate the pH at equivalence. The pK, of ethylamine is 3.19.

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 HCI solution added.
