उत्तर
When lead nitrate solution is treated with calcium chloride solution it forms white ppt. of lead chloride and calcium nitrate
CaCl2(s) → Ca2+(aq) + Cl-(aq)
\[\ce{Pb(NO3)2(aq) -> Pb^{2+}(aq) + NO^{2-}_{3}(aq)}\]
\[\ce{Pb^{2+}(aq) + NO^{2-}_{3}(aq) + Ca^{2+}(aq) + Cl-(aq) -> PbCl2 + Ca(NO3)2}\]
On further heating and cooling the products, calcium nitrate decomposes upon heating to release nitrogen dioxide:
2Ca(NO3)2 → 2CaO + 4NO2 + O2
