===Aqueous chemistry===
Strong acids dissolve gallium, forming gallium(III) salts such as [[gallium(III) nitrate|{{chem|Ga(NO|3|)|3}}]] (gallium nitrate). [[Aqueous]] solutions of gallium(III) salts contain the hydrated gallium ion, {{chem|[Ga(H|2|O)|6|]|3+}}.<ref name="wiberg_holleman">{{cite book |title= Inorganic chemistry |author1= Wiberg, Egon |author2= Wiberg, Nils |author3= Holleman, Arnold Frederick |publisher= Academic Press |date= 2001 |isbn= 978-0-12-352651-9}}</ref>{{rp|1033}} [[Gallium(III) hydroxide]], {{chem|Ga(OH)|3}}, may be precipitated from gallium(III) solutions by adding [[ammonia]].
