Titration curve for triprotic acid

WebThe titration of a weak acid with a strong base (or of a weak base with a strong acid) is somewhat more complicated than that just discussed, but it follows the same general principles. Let us consider the titration of 25.0 mL of 0.100 M acetic acid (a weak acid) with 0.100 M sodium hydroxide and compare the titration curve with that of the ... 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.
