Zinc sulfate reacts with ammonia, 4 of 5. 1M solution of ammonium hydroxide (NH4OH) is poured into a beaker containing 0.2M solution of zinc sulfate (ZnSO4). White zinc hydroxide (Zn(OH)2) is formed: ZnSO4 + NH4OH -> Zn(OH)2 + (NH4)2SO4 (photos 1-3). Then concentrated (5.8M) ammonia is poured in excess, zinc hydroxide is dissolved to produce a clear solution of tetraamminezinc(II) complex ion, [Zn(NH3)4)]2+ (photos 4-5). | |
