Chemical compound
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]
