Vedclass · Answer

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