Vedclass · Answer

(B) Pure $N_2$ is prepared by the thermal decomposition of sodium azide or barium azide. However,in the laboratory,it is commonly prepared by the reaction of aqueous solutions of ammonium chloride $(NH_4Cl)$ and sodium nitrite $(NaNO_2)$: $NH_4Cl(aq) + NaNO_2(aq) \rightarrow N_2(g) + 2H_2O(l) + NaCl(aq)$. This reaction produces $N_2$ gas.
