Final answer:
In the reaction between ammonium phosphate and lead(II) nitrate, ammonium nitrate and lead phosphate are produced, with lead phosphate precipitating as a solid. The correct option is A) Ammonium nitrate + Lead phosphate.
Step-by-step explanation:
When ammonium phosphate reacts with lead(II) nitrate, a double displacement reaction occurs where the cations and anions exchange partners. Based on solubility rules, lead phosphate is insoluble and will precipitate from the solution, while ammonium nitrate will remain in the aqueous phase.
The balanced equation for this reaction is:
3(NH4)2PO4(aq) + 3Pb(NO3)2(aq) → Pb3(PO4)2(s) + 6NH4NO3(aq)
Therefore, the final answer to which product is formed when ammonium phosphate reacts with lead(II) nitrate is: A) Ammonium nitrate + Lead phosphate.
