Question:
Identify A and B from the following reaction:\
NaNO3(\xrightarrow{\Delta}\) xA + yB
Identify A and B from the following reaction:\
NaNO3(\xrightarrow{\Delta}\) xA + yB
Show Hint
Nitrates of alkali metals decompose to nitrites and oxygen.
Updated On: Jan 6, 2026
NaNO2, O2
Na2O, NO2
Na2O, NO
Na, NO2
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
On thermal decomposition, sodium nitrate (NaNO\textsubscript{3}) gives sodium nitrite (NaNO\textsubscript{2}) and oxygen. This is a standard thermal decomposition reaction.
\[2NaNO_3 \xrightarrow{\Delta} 2NaNO_2 + O_2\]
\[2NaNO_3 \xrightarrow{\Delta} 2NaNO_2 + O_2\]
