Identification
Name: OH-
Description:In chemistry, hydroxide is the most common name for the diatomic anion OH, consisting of oxygen and hydrogen atoms, usually derived from the dissociation of a base. It is one of the simplest diatomic ions known. Hydroxide ion is a kind of ligand. It donates one pair of electrons, behaving as a Lewis base. Examples include the aluminate ion [Al(OH)4]- and aurate ion [Au(OH)4]-.
