$KNO_3$

Vedclass · Answer

(A) All alkali metal nitrates (except $LiNO_3$) decompose upon strong heating to produce the corresponding nitrite and $O_2$.$2KNO_3 	o 2KNO_2 + O_2$In contrast,nitrates of heavy metals (like $Pb$,$Ca$,$Ag$) decompose to produce metal oxides,nitrogen dioxide $(NO_2)$,and oxygen $(O_2)$:$2Pb(NO_3)_2 	o 2PbO + 4NO_2 + O_2$$2Ca(NO_3)_2 	o 2CaO + 4NO_2 + O_2$$2AgNO_3 	o 2Ag + 2NO_2 + O_2$Since $KNO_3$ produces only $KNO_2$ and $O_2$,it does not produce $NO_2$.

Which of the following salts does not produce nitrogen dioxide $(NO_2)$ upon heating?
