Here is a list from a search: For phosphoric acid, H3PO4, the pKa’s are: pKa 1=2.2, pKa 2=7.2, pKa3 =12.7. The only proton left on HPO4(2-) will only come off when the solution is more basic than pH 12.7. realistic 2v2 Aug 11, 2021 · What is the conjugate acid of HPO4^2-? The pH gives the [H3O+1] and the [OH-1] by using. Kw = [H3O+1] [OH-1] = 1.0 X 10-14. Since [OH-1] = [HPO4-2] at the equivalence point, the Kb for the conjugate base can be calculated. An important relationship between Ka for the acid and Kb for its conjugate base is Kw = Ka x Kb. This allows Ka3 to be calculated.What is the conjugate base of the Bronsted-Lowry acid HPO4^-2?
