WebA titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its end point. WebFormulas, Vocabulary, and Concepts for Analyzing a Polyprotic Acid Titration Curve. Polyprotic acids, such as sulfuric and phosphoric acid, have multiple ionizable hydrogens, …
WebTitration calculations generally involve this equation: M A ×V A =M B ×V B. M A is the molarity of the acid, while M B is the molarity of the base. V A and V B are the volumes of the acid and base, respectively. You want to measure the volumes at the endpoint of the titration, when the acid and base have neutralized each other. WebA titration of the triprotic acid H3PO4 with NaOH is illustrated in Figure 7.4.2 and shows two well-defined steps: the first midpoint corresponds to pKa 1, and the second midpoint …
