उत्तर
Distinguish between zinc ion and lead ion.
- \[\ce{ZnSO4 + 2NH4OH -> Zn(OH)2 v + (NH4)2SO4}\]
Zn(OH)2 forms white gelatinous precipitate. In the presence of excess of ammonium hydroxide these precipitates get dissolved. - \[\ce{Pb(NO3)2 + 2NH4OH -> Pb(OH)2 v + 2NH4NO3}\]
Pb(OH)2 forms white precipitate. This precipitate is insoluble in the presence of excess of ammonium hydroxide.
