The metal nitrate that liberates \( \mathrm{NO}_{2} \) on heating

A
\( \mathrm{KNO}_{3} \)
B
\( \mathrm{RbNO}_{3} \)
C
\( \mathrm{NaNO}_{3} \)
Correct answer
D
\( \mathrm{LiNO}_{3} \)

Solution

(D)
\( 4 \mathrm{LiNO}_{3} \rightarrow 2 \mathrm{Li}_{2} \mathrm{O}+4 \mathrm{NO}_{2}+\mathrm{O}_{2} \)

Hence, the correct answer is option: 'D'.
