hydroxide

noun    (Concise Encyclopedia)

Any compound with one or more functional groups made up of one atom each of hydrogen and oxygen, bonded together and acting as the hydroxide anion (OH). Hydroxides include the familiar alkalies of laboratory and industrial processes. Those of the alkali metals (lithium, sodium, potassium, rubidium, and cesium), the strongest bases, are the most stable and soluble; those of the alkaline earth metals (calcium, barium, and strontium), also soluble strong bases, are less stable. The hydroxides of most other metals are only slightly soluble but neutralize acids; some are “amphoteric,” reacting with both acids and bases. In compounds in which OH is un-ionized and covalently bonded (e.g., in methanol, CHOH), it is known as a hydroxyl group.
