Titrating 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 fo.
Titration Of A Polyprotic Acids Chemistry Steps This lesson follows what is present in the sample flask at each point in the titration of a polyprotic weak acid with a strong base, emphasizing what mathema. Because hpo 4 2 is a very weak acid, the third equivalence point, at ph ≈ 13, is not well defined. (this is because the maximum ph that can be achieved with 0.100 m naoh is 13.) the titration curve for the reaction of a polyprotic base with a strong acid is similar, but inverted on the ph scale. the initial ph is high; as acid is added, the. The weak polyprotic acid (analyte) is in green and is titrated with teh strong base (the titrant) in red. (cc by; heather yee via libretexts) when an acid is titrated, there is an equivalence, or stoichiometric, point, which is when the moles of the strong base added equal of the moles of weak acid present. however, when a weak polyprotic acid.

The curve for the titration of 25.0 ml of 0.100 m h 3 po 4 solution with 0.100 m naoh. species in solution at each midpoint are shown. note the two distinct equivalence points corresponding to deprotonation of h 3 po 4 at ph ≈ 4.6 and h 2 po 4– at ph ≈ 9.8. because hpo 42 is a very weak acid, the third equivalence point, at ph ≈ 13, is. You need to solve for the ka k a value. to do that you use. ka = [h3o ][a−] [ha] (2) (2) k a = [h 3 o ] [a −] [h a] another necessary value is the pka p k a value, and that is obtained through pka = −logka p k a = − l o g k a. the procedure is very similar for weak bases. the general equation of a weak base is.
