Vedclass · Answer

(D) Very pure nitrogen gas is obtained by the thermal decomposition of sodium azide $(NaN_3)$ or barium azide $(Ba(N_3)_2)$.The reaction for sodium azide is:$2 NaN_3 \xrightarrow{\Delta} 2 Na + 3 N_2$While other reactions like the decomposition of ammonium nitrite also produce $N_2$,the thermal decomposition of azides is the standard laboratory method for preparing ultra-pure nitrogen.
