Question

Name a nitrate which, on heating leaves no residue behind.

Answer 1

Ammonium nitrate is the nitrate that does not leave residue behind on heating.

• Ammonium nitrate gives out nitrous oxide and water vapor.
• The heating of ammonium nitrate is very explosive, we get the smell of sweet nitrous gas
• $\underset{\mathrm{Nitrate}}{\underset{\mathrm{Ammonium}}{{\mathrm{NH}}_4{\mathrm{NO}}_3}}\left(\mathrm{s}\right)\stackrel{∆}{\to }\underset{\mathrm{Oxide}}{\mathrm{N}\underset{\mathrm{Nitrous}}{{}_2\mathrm{O}\left(\mathrm{g}\right)}}+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$
