Used in the production of basic lead phosphonate PVC stabilizer, aminomethylene phosphonic acid and hydroxyethane diphosphonic acid. 1.4 * 10^(-4) All you have to do in order to find the value of the acid dissociation constant, K_a, is to write a balanced chemical equation for the equilibrium that is established when lactic acid, "HC"_3"H"_5"O"_3, is added to water. The dissociation constants of phosphoric acid (pK 1 and pK 2) in water-dimethylformamide (DMFA) mixtures (00.65 mole fractions of DMFA) were dissociation equation for h3po4 H2BO3- H+ + Unlike a strong acid like HCl which dissociates in water to make H+ and Cl-, boric acid doesn't dissociate at all.
