Gallium hydroxide, Ga(OH)
3 is formed as a gel following the addition of ammonia to Ga
3+ salts.

Gallium hydroxide is
amphoteric
In chemistry, an amphoteric compound () is a molecule or ion that can react both as an acid and as a base. What exactly this can mean depends on which definitions of acids and bases are being used.
One type of amphoteric species are amphip ...
. In strongly acidic conditions, the gallium
ion
An ion () is an atom or molecule with a net electrical charge.
The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by conven ...
, Ga
3+ is formed. In strongly basic conditions, Ga(OH)
4− is formed. Salts of Ga(OH)
4− are sometimes called
gallate
Gallate may refer to:
* gallic acid salt, a salt or ester of gallic acid
* gallium salt, a salt containing oxyanions of gallium
