hydroksidiioni
Hydroksidiioni (hydroxide ion; OH−) is an inorganic anion consisting of a hydroxyl group (OH) bearing a negative charge. It is the conjugate base of water and a key participant in acid–base chemistry, especially in aqueous solutions and industrial processes.
Structure and properties: The hydroxide ion has a bent geometry around the oxygen atom, with the negative
Chemistry: As a Brønsted–Lowry base, OH− accepts a proton to form water: OH− + H+ → H2O. In
Occurrence and production: Hydroxide occurs in minerals such as brucite Mg(OH)2 and portlandite Ca(OH)2. Industrially, it
Applications and safety: OH− is central to chemical manufacturing, water treatment, and pH control. It is highly
