Identify A and B from the following reaction NaNO 3 ⟶ ∆ xA + yB
Options
- ANaNO 2 , O 2
- BNa 2 O , NO 2
- CNa 2 O , NO
- DNa , NO 2
Correct answer
A. NaNO 2 , O 2
Step-by-step solution
Almost all nitrates liberates the nitrogen dioxide gas on heating. But alkali metal nitrates liberates oxygen gas on heating except lithium nitrate. Hence, sodium nitrate gives sodium nitrite and oxygen gas. NaNO 3 → ∆ NaNO 2   +   1 2 O 2
