Web25 mai 2024 · Updated on May 25, 2024. The acid dissociation constant is the equilibrium constant of the dissociation reaction of an acid and is denoted by K a. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. K a is commonly expressed in units of mol/L. Web23 mar. 2024 · The dissociation constant K a is [H3O+] [CH 3 CO 2-] / [CH 3 CO 2) H]. K a = x 2 / (0.9 - x) As noted above, [H3O+] = 10 -pH. Since x = [H3O +] and you know the pH of the solution, you can write x = 10 -2.4. It is now …

Web22 oct. 2024 · K = [H3O +][A −] [HA][H2O] But we can consider the water concentration constant because it is much greater than of acid that has ionized. There are two factors at work here, first that the water is the solvent and so [H 2 O] is larger than [HA], and second, that [HA] is a weak acid, and so at equilibrium the amount ionized is smaller than [HA].
