'''Gallium hydroxide''' is an [[inorganic compound]] with the [[chemical formula]] {{chem2|Ga(OH)3|auto=1}}. It is formed as a [[gel]] following the addition of [[ammonia]] to {{chem2|Ga(3+)}} salts.<ref name = "Downs">Anthony John Downs, (1993), ''Chemistry of Aluminium, Gallium, Indium, and Thallium'', Springer, {{ISBN|978-0-7514-0103-5}}</ref> It is also found in nature as the rare [[mineral]] söhngeite which is reported to contain octahedrally [[Coordination number|coordinated]] [[gallium]] atoms.<ref name = "Scott"> Crystal Structure of a new mineral söhngeite, J.D. Scott, The American Mineralogist, (1971), 56, 355</ref>
Gallium hydroxide is [[amphoteric]]. In strongly [[Acid|acidic conditions]], the gallium [[ion]], {{chem2|Ga(3+)}} is formed. In strongly [[Base (chemistry)|basic conditions]], {{chem2|[Ga(OH)4]−}} (tetrahydroxogallate(III)) is formed. Salts of {{chem2|[Ga(OH)4]−}} are sometimes called [[Gallium salt|gallate]]s.<ref name = "Downs" />
