Web4 sep. 2024 · Hydroxide or hydroxyl ion is a diatomic anion with chemical formula OH−. It consists of an oxygen and hydrogen atom held together by a covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile and a catalyst. Web15 okt. 2024 · PAA, which is formed by the reaction of acetic acid (AA) and hydrogen peroxide (HP) with acid catalysts, contains a perhydroxyl group (-OOH) in place of a hydroxyl group in its parent acid. The powerful oxidant includes a hydroxonium ion (HO+) produced from the heterolytic cleavage of the peroxy bond.
