Diprotic Acid is the fourth model in the Bronsted-Lowry Acid-Base Package. The model demonstrates the behavior of an acid that had two protons to donate to a base instead of just one. When users plot the pH curve and the Titration curve for this diprotic acid, they may be surprised to see how much it differs from the curves of a monoprotic acid. Several Ka values are included with the model so users can observe how each unique value affects the acid's behavior.
