Vedclass · Answer

(D) Very pure nitrogen can be obtained by the thermal decomposition of sodium or barium azide. $2NaN_3 \xrightarrow{573 \ K} 2Na + 3N_2$ Azide salt of barium can be obtained in the purest form as well as the decomposition product contains solid $Ba$ as a by-product along with gaseous nitrogen,hence no additional step of separation is required. $Ba(N_3)_2 \xrightarrow{	ext{heat}} Ba + 3N_2$ Hence,option $D$ is correct.

Extra pure $N_2$ can be obtained by heating
