WebAn acid is a chemical that dissociates in an aqueous solution, producing the hydrogen ion H + (a proton), according to Arrhenius’s original molecular definition: HA ⇌ A– + H+. H2O ⇌ H+ + OH–. A dissociation constant is the equilibrium constant for this dissociation reaction. Because the released proton reacts with a water molecule to ... WebIn the autoionization of water, a proton is transferred from one water molecule to another to produce a hydronium ion (H₃O⁺) and a hydroxide ion (OH⁻). The equilibrium expression for this reaction is Kw = [H₃O⁺] [OH⁻], where Kw is the autoionization constant for water. At 25°C, the value of Kw is 1.0 x 10⁻¹⁴.
