उत्तर
\[\ce{Pb(NO3)2 + 2NH4OH -> \underset{Chalky white ppt.}{Pb(OH)2↓} + 2NH4NO3}\]
Insoluble in excess of NH4OH,
\[\ce{ZnSO4 + 2NH4OH -> \underset{White gelatinous ppt.}{Zn(OH)2↓} + (NH4)2SO4}\]
With the excess of NH4OH ppt. dissolves.
\[\ce{Zn(OH)2 + (NH4)2SO4 + 2NH4OH -> \underset{Tetra amine zinc sulphate}{[Zn(NH3)4]SO4} + 4H2O}\]
