Question

The gas produced by treating an aqueous solution of ammonium chloride with sodium nitrite is

• A. $NH_3$
• B. $N_2$
• C. $N_2O$
• D. $Cl_2$

Answer 1

Answer: (B)

$N_2$

Answer 2

$N_2$ gas is produced by treating an aqueous solution of ammonium chloride with sodium nitrite.

$NH_4Cl(aq)$ + NaNo_2(aq)$$⟶$$N_2(g) $+ 2H_2O(l)$ $+ NaCl(aq)$
Ammonium chloride Sodium nitrite Nitrogen gas Water Sodium chloride
