Calculate ph of weak base

WebTranscript. In a weak base-strong acid titration, the acid and base will react to form an acidic solution. A conjugate acid will be produced during the titration, which then reacts with water to form hydronium ions. This results in a solution with a pH lower than 7. An example of this is the titration of hydrochloric acid (strong acid) into ... WebIn this JC2 webinar we want to learn how to calculate the pH of a weak base. The method is very similar to finding the pH of a weak acid. Let's take a look at the question. Since ammonia is a weak base, it will be partially dissociated. We can work out the concentrations of all the species at equilibrium via the ICE table.
