Zinc(II) ion reacts with aqueous ammonia to precipitate white gelatinous Zn(OH)2: Zn2+(aq) + 2NH3(aq) + 2H2O(l) <==> Zn(OH)2(s) + 2NH4+(aq)
The zinc(II) hydroxide precipitate dissolves in excess ammonia: Zn(OH)2(s) + 4NH3(aq) <==> [Zn(NH3)4]2+(aq) + 2OH-(aq)
The zinc(II) hydroxide precipitate also dissolves in hydroxide: Zn(OH)2(s) + 2OH-(aq) <==> [Zn(OH)4]2-(aq)
It also react with acids!
