What tests would you use to identify a solution of Ag3PO4?

Answer 1

To identify a solution of Ag3PO4 (silver phosphate), you could perform a qualitative test for silver ions (Ag⁺) and phosphate ions (PO4³⁻). For silver, adding hydrochloric acid (HCl) would result in the formation of a white precipitate of silver chloride (AgCl) if Ag⁺ is present. For phosphate, adding ammonium molybdate and heating the solution would produce a yellow precipitate of ammonium phosphomolybdate if PO4³⁻ ions are present.

Answer 2

To identify a solution of Ag3PO4, you can perform a qualitative test using a phosphate test, such as adding ammonium molybdate and nitric acid, which will produce a yellow precipitate if phosphate ions are present. Additionally, you could use a silver ion test; adding a chloride solution may result in the formation of a white precipitate of AgCl, indicating the presence of silver ions. Finally, spectroscopy methods like UV-Vis could help confirm the presence of Ag3PO4 by analyzing its characteristic absorption peaks.
