Nitrogen dioxide is not produced on heating
- A \(\mathrm{KNO}_{3}\)
- B \(\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}\)
- C \(\mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}\)
- D \(\mathrm{AgNO}_{3}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{KNO}_{3}\)
Step-by-step Solution
Detailed explanation
Only KNO \(_{3}\) on heating do not give \(\mathrm{NO}_{2}\), but all other give (a) \(2 \mathrm{KNO}_{3} \stackrel{\Delta}{\longrightarrow} 2 \mathrm{KNO}_{2}+\mathrm{O}_{2}\) (b)…
