Question

${\mathrm{NH}}_4{\mathrm{NO}}_3$ on heating gives_______

Answer 1

Ammonium nitrate (${\mathrm{NH}}_4{\mathrm{NO}}_3$) :-

1. It is actually an ionic salt which is made up of the ammonium cation $\left({\mathrm{NH}}_4^{+}\right)$ and the nitrate anion (${\mathrm{NO}}_3^{-}$)
2. On the heating of ${\mathrm{NH}}_4{\mathrm{NO}}_3$, the compound will decompose for the formation of Nitrous oxide (${\mathrm{N}}_2\mathrm{O}$) and water.
3. Reaction involved: $\underset{\mathrm{Ammonium}\mathrm{nitrate}}{{\mathrm{NH}}_4{\mathrm{NO}}_{3\left(\mathrm{s}\right)}}\to \underset{\mathrm{Nitrous}\mathrm{oxide}}{{\mathrm{N}}_2{\mathrm{O}}_{\left(\mathrm{g}\right)}}+\underset{\mathrm{Water}}{{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{l}\right)}}$

Therefore, ${\mathrm{NH}}_4{\mathrm{NO}}_3$ on heating gives Nitrous oxide and Water.
