The Common Ion Effect: Calculation of pH. When a weak, nitrogen base is protonated, the resulting conjugate acid is given the "ium" suffix to show that it has been protonated and has an overall +1 charge. Thus, the weak base ammonia is protonated to form the ammonium (NH4+) cation. What is the pH of a 0.68 M solution of (CH3)2NH that is also 0.65 M in dimethylammonium sulfate, the salt of it's conjugate acid? The Kb for (CH3)2NH = 5.4...
