Question

Identify the gas evolved and give the chemical test when sodium nitrite is heated with ammonium chloride?

Answer 1

1. In these reaction when sodium nitrite is heated with ammonium chloride nitrogen gas is release with pungent smell.
2. The main product formed in the reaction are the white crystals of sodium chloride along with the water molecules, further releasing nitrogen molecules.

$$\begin{gathered} {\mathrm{NaNO}}_2+{\mathrm{NH}}_4\mathrm{Cl}\stackrel{∆}{\to }\mathrm{NaCl}+{\mathrm{N}}_2+2{\mathrm{H}}_2\mathrm{O} \\ (\mathrm{sodium}(\mathrm{ammonium}(\mathrm{sodium}(\mathrm{nitrogen})(\mathrm{water}\left) \\ \mathrm{nitrite}\right)\mathrm{chloride})\mathrm{chloride}) \end{gathered}$$
