WebTitrating a polyprotic acid with a strong base produces a pH curve with as many equivalence points as there are acidic protons on the acid. The pKₐ values for these protons can be estimated from the corresponding half-equivalence points on the curve, where pH = pKₐ. Created by Jay. Sort by: Top Voted Questions Tips & Thanks WebLab: Titration Purpose: Explore the concentration of an acid by titrating it with a base of known concentration. Time: Approximately 45 minutes Question: How can the strength of an acid be determined using titration? Hypothesis: If you know the volume and concentration of a base that completely neutralizes an acid, then you can determine the concentration of …
