Question
- A. NH3 + HNO3 → NH4NO3 + H2O
- B. NH3 + HNO3 → NH4NO3
- C. NH3 + HNO3 → NH4NO3 + H2O2
- D. NH3 + HNO3 → NH4NO3 + H2O + O2
Answer
The correct option is NH3 + HNO3 → NH4NO3 + H2O. 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 NH3 + HNO3 → NH4NO3 + H2O. NH3 + HNO3 → NH4NO3 + H2O 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.
Common mistake
Common Mistake in Preparing Ammonium Salts
Students often confuse the preparation of ammonium salts with the preparation of other types of salts, leading to incorrect methods being used.
Focus on the specific reactants and conditions required for ammonium salt preparation, such as using ammonia and an appropriate acid.
