WebAboutTranscript. In 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 … The hydroxide ion is a natural part of water because of the self-ionization reaction in which its complement, hydronium, is passed hydrogen: H3O + OH ⇌ 2H2O The equilibrium constant for this reaction, defined as Kw = [H ][OH ] has a value close to 10 at 25 °C, so the concentration of hydroxide ions in pure … Meer weergeven Hydroxide is a diatomic anion with chemical formula OH .
