Gallium hydroxide, Ga(OH)₃ is formed as a gel following the addition of ammonia to Ga³⁺ salts. It is also found in nature as the rare mineral söhngeite which is reported to contain octahedrally coordinated gallium atoms Gallium hydroxide is amphoteric. In strongly acidic conditions, the gallium ion, Ga³⁺ is formed. In strongly basic conditions, Ga(OH)₄⁻ is formed. Salts of Ga(OH)₄⁻ are sometimes called gallates.
