$KNO_3$

Vedclass · Answer

(A) Heating alkali metal nitrates like $KNO_3$ results in the formation of the corresponding nitrite and oxygen gas: $2KNO_3 \rightarrow 2KNO_2 + O_2$. Heavy metal nitrates like $Pb(NO_3)_2$,$Ca(NO_3)_2$,and $AgNO_3$ decompose upon heating to produce nitrogen dioxide $(NO_2)$,oxygen,and the corresponding metal oxide or metal: $2Pb(NO_3)_2 \rightarrow 2PbO + 4NO_2 + O_2$ $2Ca(NO_3)_2 \rightarrow 2CaO + 4NO_2 + O_2$ $2AgNO_3 \rightarrow 2Ag + 2NO_2 + O_2$ Therefore,$KNO_3$ does not produce $NO_2$.

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