The concentration (weight %) of nitric acid produced by the oxidation of ammonia and absorption of nitrogen oxides with water is about ____________ percent?
Correct answer: A. 60
- A. 60
- B. 30
- C. 95
- D. 100
Explanation
Ammonia oxidation followed by absorption of nitrogen oxides in water commonly produces nitric acid of about 60 weight percent. Concentrations near 95 percent require additional concentration or a different process arrangement.
