$KNO_3$

Vedclass · Answer

(A) Nitrogen dioxide $(NO_2)$ is not produced by heating $KNO_3$. The thermal decomposition reactions are as follows:$1) \ 2 KNO_3 \rightarrow 2 KNO_2 + O_2$ (Note: At very high temperatures,$KNO_2$ may further decompose,but $NO_2$ is not the primary product).$2) \ 2 Pb(NO_3)_2 \rightarrow 2 PbO + 4 NO_2 + O_2$$3) \ 2 Cu(NO_3)_2 \rightarrow 2 CuO + 4 NO_2 + O_2$$4) \ 2 AgNO_3 \rightarrow 2 Ag + 2 NO_2 + O_2$As shown,$Pb(NO_3)_2$,$Cu(NO_3)_2$,and $AgNO_3$ all yield $NO_2$ upon heating,whereas $KNO_3$ does not.
