NH3(aq)+the following chemicals 會出咩色precipitate和咩色solution?

NH3+Ag : colourless
NH3+Ba : colourless
NH3+Ca : colourless
NH3+Cr : green
NH3+Cu : blue (or green)
NH3+Fe(II) : pale green
NH3+Fe(III) : yellow / brown
NH3+K : colourless
NH3+Mg : colourless
NH3+Mn(II) : very pale pink
NH3+Na : colourless
NH3+NH4 : colourless
NH3+Ni(II): green
NH3+Pb : colourless
NH3+Sn : colourless
NH3+Zn : colourless

Cr, Cu, Fe(II), Fe(III), Mn(II), Ni(II) should have these colourothers dunno

NH3 融在水中會變成NH4OH
Reaction : NH3 + H2O ---> NH4OH precipitate excess
Ag+ + NH4OH ---> AgOH which is white
Ba(OH)2 white
Ca(OH)2 white
Cr(OH)3 green
Cu(OH)2 blue @ blue solution
Fe2+ green
Fe3+ yellow
K+ colourless
Mg2+ white
Mn2+ Very pale pink
Na2+ Colourless
NH4+ No such reaction
Ni2+ green
Pb2+ white
Sn2+ white
Zn 2+ white @colourless

Hope this help

The above person gives you the wrong answer, he doesn't even know NH3 will form NH4OH in water.....
