Vedclass · Answer

(B) The thermal decomposition of $LiNO_3$ produces $Li_2O$,$NO_2$ (brown gas),and $O_2$.$4LiNO_3 \xrightarrow{\Delta} 2Li_2O + 4NO_2 + O_2$.$KNO_3$ decomposes to form $KNO_2$ and $O_2$ (colorless gas),so it does not liberate a brown gas.$2KNO_3 \xrightarrow{\Delta} 2KNO_2 + O_2$.Reaction of $Zn$ with conc $HNO_3$ produces $NO_2$ (brown gas).$Zn + 4HNO_3 \rightarrow Zn(NO_3)_2 + 2NO_2 + 2H_2O$.Addition of conc $H_2SO_4$ on $NaNO_3$ produces $HNO_3$ vapor,which decomposes to $NO_2$ (brown gas).$NaNO_3 + H_2SO_4 \rightarrow NaHSO_4 + HNO_3$ followed by $4HNO_3 \rightarrow 4NO_2 + 2H_2O + O_2$.
