Hydroxide ions are released by the resin as anions are adsorbed from the liquid phase. The effect is elimination of acidity in the liquid and conversion of the resin to a salt form. Typically, the resin is restored to the OH? form with a 4% solution of NaOH.
The hydroxide form is also used in salt splitting applications.
resin ? N(CH3)3OH^-+Na+ + Cl^- ?
resin ? N(CH3)3Cl^- + Na⁺ + OH^-
Salt forms of a strong base anion exchangerare used to remove other anions for which the resin has greater selectivity.
2 resin ? N(CH3)3Cl^- +2Na+SO4^2- ?
(resin ? N(CH3)3)2SO4^2- +2 Na+ +2Cl^-

ChEBI: Hydroxide is an oxygen hydride. It has a role as a mouse metabolite. It is a conjugate base of a water.
