Example Problem: Consider The Titration of 100.0 mL of 0.200 M CH3NH2 by 0.100 M HCl. Calculate The pH After 65.0 mL of HCl Added. (Kb for CH3NH2 = 4.4 x 10-4): 10.96 - correct answer. 9.75. 7.00. 3.68. 2.54.
You are diligently doing an assignment when a question comes up that had a pH of -1. Is this likely a typo by a tired instructor, or is this number indeed possible? Explain clearly, using an example if need.
