WebStrong acids (such as HCl, HBr, HI, HNO₃, HClO₄, and H₂SO₄) ionize completely in water to produce hydronium ions. The concentration of H₃O⁺ in a strong acid solution is therefore equal to the initial concentration of the acid. For example, a solution of 0.1 M HNO₃ contains 0.1 M H₃O⁺ and has a pH of 1.0. Created by Jay. Webp K a = − log K a. Acid dissociation constant is the equilibrium constant of the dissociation of ions of an acid in an aqueous solution. Consider a weak acid H A. Weak acids do not dissociate completely in aqueous solution. The equilibrium for the dissociation of such acids can be expressed as. H A + H X 2 O ↽ − − ⇀ H X 3 O X + + A X −.
WebJan 31, 2024 · For a weak acid to be coaxed to give up a proton, a reasonably strong base (like OH-) should be added. So at low pH, the acid exists just as HA. So at low pH, the … WebJan 31, 2024 · All acids of the generic formula HA have pKa. HA − ⇀ ↽ − H + + A −. The equilibrium constant for this simplified reaction can be written as. Keq = [H +][A −] HA Ka = [HA]Keq = [H +][A −] pKa = − logKa. The pK a becomes a simple measure of the strength of an acid. The stronger the acid, the larger the K a and the smaller the pK a.
