When aqueous solutions of silver nitrate and sodium phosphate are combined, silver phosphate precipitates out of solution as a solid, and sodium nitrate remains dissolved. The net ionic equation shows that silver and phosphate ions react to form solid silver phosphate.

1. When aqueous solutions of silver(I) nitrate and sodium phosphate are combined, solid silver(I)
phosphate and a solution of sodium nitrate are formed. The net ionic equation for this reaction is:
