Question

Name the gas evolved when the following mixture is heated

Sodium nitrite and ammonium chloride

Answer 1

Correct answer- Nitrogen gas is evolved

• When sodium nitrite react with ammonium chloride, ammonium nitrite is formed.
• NaNO₂(aq)+ NH₄Cl(aq) $\stackrel{∆}{\to }$ NH₄NO₂(aq)+ NaCl(aq).
• Ammonium nitrite is unstable and dissociate again to form nitrogen gas.
• NH₄NO₂(aq)$\to$N₂(g)+ H₂O(l)
