Vedclass · Answer

(D) Lithium nitrate $(LiNO_3)$ is the only alkali metal nitrate that decomposes to its oxide $(Li_2O)$ upon strong heating.The reaction is: $4LiNO_3(s) \xrightarrow{\Delta} 2Li_2O(s) + 4NO_2(g) + O_2(g)$.Other alkali metal nitrates like $NaNO_3$ and $KNO_3$ decompose to their respective nitrites and oxygen gas: $2MNO_3(s) \xrightarrow{\Delta} 2MNO_2(s) + O_2(g)$ (where $M = Na, K$).
