A chemist titrates 190.0 mL of a 0.3300M methylamine (CH3NH2) solution with 0.2028M HBr solution at 25 °C. Calculate the pH at equivalence. The pK of methylamine is 3.36. 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. PH = 0
