WebTriprotic Acids. Our techniques for working diprotic acid or diprotic base equilibrium problems can be applied to triprotic acids and bases as well. To illustrate this, let's calculate the H 3 O + , H 3 PO 4, H 2 PO 4-, HPO 42- , and PO 43- concentrations at equilibrium in a 0.10 M H 3 PO 4 solution, for which Ka1 = 7.1 x 10 -3, Ka2 = 6.3 x 10 ... WebThe ionization of acetic acid is incomplete, and so the equation is shown with a double arrow. The extent of ionization of weak acids varies, but is generally less than 10%. A 0.10 M solution of acetic acid is only about 1.3% ionized, meaning that the equilibrium strongly favors the reactants.
