WebTypically, we can calculate the pH based on the first dissociation. The reason is that >>pK_ {a2}">pKa1>>>pKa2. So, the bulk of the hydrogen ions will come from the first … WebThe lab aimed to observe and determine acid-base titrations using virtual lab software. We observed three different acids mixed with sodium hydroxide for the experiment to record how their pH reacted and changed throughout the trials. The acids used were hydrochloric acid, which was the strong monoprotic acid, phosphoric acid, which was the weak … daffy vance
