gallium in the Earth's crust.Gallium hydroxide is very rarely seen as a discrete mineral called söhngeite; much more commonly, gallium replaces
aluminium inore s such asbauxite . Rich sources may contain almost 1% Ga replacing Al, but a more typical value is a hundred times less.Gallium hydroxide is
amphoteric . In strongly acid conditions, galliumion , Ga3+ is formed; in strongly basic conditions, Ga(OH)4-, is formed.Salts of Ga(OH)4- are sometimes called
gallate s.References
