metal phosphate | silver phosphate is a metal phosphate salt of the chemical formula Ag3PO4. Molecular weight 418.58. Yellow odorless cubic crystal powder. Brown when exposed to heat or sunlight. The melting point of 849 deg C, the relative density of 6.37025. Insoluble in water, slightly soluble in dilute acetic acid, soluble in dilute nitric acid, ammonia, potassium cyanide solution, ammonium carbonate and sodium thiosulfate solution. preparation method: obtained by the interaction of silver nitrate and sodium phosphate solution. Silver pyrophosphate and disodium hydrogen phosphate solution boiling yellow silver phosphate. purposes: silver phosphate can be used for the preparation of photographic industry commonly used silver bromide, silver iodide emulsion, also as a catalyst and drugs. Alkyl halides react with silver phosphate to form neutral phosphate. |
