Concentrated nitric acid, upon long standing, turns yellow-brown due to the formation of
- A NO
- B NO2
- C N2O
- D N2O4
Answer & Solution
Correct Answer
(B) NO2
Step-by-step Solution
Detailed explanation
Nitric acid decomposes in sunlight as per reaction
Yellow colour is due to dissolved NO2(liq.) NO2(g) is brown in colour but it is yellow in dissolved form.
