Question
How is ammonia used in the production of nitric acid?
Answer
Ammonia is reacted with oxygen in the presence of a catalyst to produce nitric acid. This process involves the oxidation of ammonia, which is a key step in the industrial synthesis of nitric acid.
Explanation
A strong answer should directly address the approved learning objective to explain that ammonia can be used to manufacture nitric acid. (Chemistry only). This question belongs to Production and uses of NPK fertilisers within The Haber process and the use of NPK fertilisers, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to chemistry only, and keeps the wording specific to AQA GCSE revision.
Common mistake
Confusing Ammonia Uses
Students often confuse the use of ammonia in making nitric acid with its use in making ammonium salts.
Remember that ammonia can be used to manufacture both nitric acid and ammonium salts, but they are distinct processes.
