H3PO4 ==> H+ + H2PO4- Ka1 H2PO4- ==> H+ + HPO42- Ka2 HPO42- ==> H+ + PO43- Ka3 Ka1 = [H+][H2PO4]/[H3PO4] Ka2 = [H+][HPO42-][H2PO4-] Ka3 = [H+][PO43-]/[HPO42-]

using chemical equations, show how the triprotic acid H3PO4 ionizes water.

H₃PO₄ ==> H⁺ + H₂PO₄^- Ka₁

H₂PO₄^- ==> H⁺ + HPO₄^2- Ka₂

HPO₄^2- ==> H⁺ + PO₄^3- Ka₃

Ka1 = [H⁺][H₂PO₄]/[H₃PO₄]

Ka2 = [H⁺][HPO₄^2-][H₂PO₄^-]

Ka3 = [H⁺][PO₄^3-]/[HPO₄^2-]
