The metal nitrate that liberates \( \mathrm{NO}_{2} \) on heating
- A \( \mathrm{KNO}_{3} \)
- B \( \mathrm{RbNO}_{3} \)
- C \( \mathrm{NaNO}_{3} \)
- D \( \mathrm{LiNO}_{3} \)
Answer & Solution
Correct Answer
(D) \( \mathrm{LiNO}_{3} \)
Step-by-step Solution
Detailed explanation
(D)
\( 4 \mathrm{LiNO}_{3} \rightarrow 2 \mathrm{Li}_{2} \mathrm{O}+4 \mathrm{NO}_{2}+\mathrm{O}_{2} \)
\( 4 \mathrm{LiNO}_{3} \rightarrow 2 \mathrm{Li}_{2} \mathrm{O}+4 \mathrm{NO}_{2}+\mathrm{O}_{2} \)
