- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Concentrated nitric acid oxidises non–metals and their compounds. Phosphorus is oxidised to phosphoric acid and nitric acid is reduced to nitrogen dioxide. The reaction is shown below. P4 + 20 HNO3→4H3PO4+20NO2+4H2O
