"A" obtained by Ostwald's method involving air oxidation of , upon further air oxidation produces "B". "B" on hydration forms an oxoacid of Nitrogen along with evolution of "A". The oxoacid also produces "A" and gives positive brown ring test. A and B respectively are:

Canvas Classes · Accepted Answer

Ostwald's process:

Step 1: 
A = NO

Step 2: 
B =

Step 3: 
- Oxoacid =  (nitric acid)
- Evolution of A = NO ✓

Brown ring test:  gives positive brown ring test (FeSO₄ +  → brown ring of ) ✓

Answer: Option (3) — NO,
