Reaction of anhydrous liquid ammonia with ortho-phosphoric acid produces____________________?
Correct answer: D. Ammonium phosphate
- A. None of these
- B. Superphosphate
- C. Triple superphosphate
- D. Ammonium phosphate
Explanation
Ammonia neutralises orthophosphoric acid to form ammonium phosphate, chiefly monoammonium or diammonium phosphate depending on the ammonia-to-acid ratio. Superphosphate products also contain calcium compounds, so they are not the direct neutralisation product here.
