Silver Phosphate

Silver phosphate is a light sensitive and water insoluble chemical compound that has been combination of silver and phosphate ions. The silver has positively charged ions and phosphate has negative charged ions. It can be dissolved in the aqueous ammonia. Gradually it evaporates from that ammoniacal solutions.  The systematic IUPAC name is known as silver phosphate. The chemical or molecular formula of silver phosphate is Ag3PO4. It is also known as argentous phosphate or phosphoric acid.
