Question
- A. React ammonia with sulphuric acid
- B. React ammonia with sulphur dioxide
- C. React ammonia with sodium sulphate
- D. React ammonia with calcium sulphate
Answer
The correct option is React ammonia with sulphuric acid. This answer is correct because it matches the approved learning objective to prepare an ammonium salt. (Chemistry only; AT 4) in the subtopic Production and uses of NPK fertilisers.
Explanation
The correct option is React ammonia with sulphuric acid. React ammonia with sulphuric acid is correct because it directly supports the approved learning objective to prepare an ammonium salt. (Chemistry only; AT 4). This belongs to the subtopic Production and uses of NPK fertilisers within The Haber process and the use of NPK fertilisers, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Production and uses of NPK fertilisers.
