Chemical compound

Gallium hydroxide is aninorganic compound with thechemical formulaGa(O H)₃. It is formed as agel following the addition ofammonia toGa³⁺ salts.^[2] It is also found in nature as the raremineral söhngeite which is reported to contain octahedrallycoordinated gallium atoms.^[3]Gallium hydroxide isamphoteric. In stronglyacidic conditions, the galliumion,Ga³⁺ is formed. In stronglybasic conditions,[Ga(OH)₄]⁻ (tetrahydroxogallate(III)) is formed. Salts of[Ga(OH)₄]⁻ are sometimes calledgallates.^[2]
