Nitric acid is produced on commercial scale in a fertiliser plant by___________________?

Correct answer: A. Oxidation of ammonia

  • A. Oxidation of ammonia
  • B. CaNO3 + H2SO4 reaction
  • C. Passing air through high voltage electric arc
  • D. None of these

Explanation

Commercial nitric acid is made by the Ostwald process, in which ammonia is catalytically oxidised to nitric oxide, then further oxidised and absorbed in water. The electric-arc route is an older, uneconomical method.
