$LiNO_3$

Vedclass · Answer

(D) Among the given nitrates,only $LiNO_3$ decomposes to give $NO_2$ on heating,whereas the nitrates of $Na, K,$ and $Rb$ decompose to form their respective nitrites and release oxygen gas.The decomposition reaction for $LiNO_3$ is:$4 LiNO_3 \xrightarrow{\Delta} 2 Li_2O + 4 NO_2 + O_2$The decomposition reaction for other alkali metal nitrates $(M = Na, K, Rb)$ is:$2 MNO_3 \xrightarrow{\Delta} 2 MNO_2 + O_2$
