Final answer:
Sodium phosphate reacts with lead(II) nitrate to form lead(II) phosphate as a precipitate and sodium nitrate as a soluble aqueous solution, but the exact balanced equation requires knowing the chemical formulas of the reactants.
Step-by-step explanation:
When sodium phosphate reacts with lead(II) nitrate, a double-replacement reaction occurs. The products of this reaction include a precipitate and a soluble compound. Based on the solubility rules and similar reactions, the products are likely to be lead(II) phosphate, which will precipitate, and sodium nitrate, which remains in an aqueous solution. However, to provide an accurate balanced chemical equation, we need the chemical formulas for the reactants. Typically, the balanced chemical equation would be written out using the correct coefficients to ensure mass conservation and charge balance.
