A chemist titrates 240.0 mL of a 0.7318 M ethylamine (C_2 H_5NH_2) solution with 0.3280 M HCl solution at 25 degree C. Calculate the pH at equivalence. The p^K_ b 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 HCl solution added.
