1 、 Fe3+ + 3NH3*H2O = Fe(OH)3 沉淀 + 3 NH4+
2 、Mg2+ + 2NH3*H2O = Mg(OH)2 沉淀 + 2NH4+
3、Ag+ + NH3*H2O = AgOH 沉淀 + NH4+
AgOH + 2NH3*H2O = 「Ag(NH3)2」- + OH- + 2H2O
4、Cu2+ + 2NH3*H2O = Cu(OH)2 沉淀 + 2NH4+
5、Al3+ + 3NH3*H2O = Al(OH)3 沉淀 + 3NH4+

1.Fe3++3NH3.H2O=Fe(OH)3↓+3NH4+
2.Mg2++2NH3.H2O=Mg(OH)2↓+2NH4+
3.Ag++NH3·H2O=AgOH↓+NH4+
AgOH+2NH3·H2O=〔Ag(NH3)2〕++OH-+2H2O
4.Cu2++2NH3.H2O=Cu(OH)2↓+2NH4+
5.Al3++3NH3.H2O=Al(OH)3↓+3NH4+
