Gallium hydroxide is an inorganic compound with the chemical formula Ga( O H)3. It is formed as a gel following the addition of ammonia to Ga3+ salts. [2] It is also found in nature as the rare mineral söhngeite which is reported to contain octahedrally coordinated gallium atoms. [3] Gallium hydroxide is amphoteric. In strongly acidic conditions, the gallium ion, Ga3+ is formed. In strongly basic conditions, [Ga(OH)4− (tetrahydroxogallate(III)) is formed. Salts of [Ga(OH)4− are sometimes called gallates. [2]
