Gallium hydroxide is an inorganic compound with the chemical formula Ga(OH)
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]
