The chemical formula for ammonium phosphate (NH4)3PO4 is an unstable compound made up of ammonium and phosphate salt.

You are watching: What is the chemical formula for ammonium phosphate

Ammonium phosphate is made by melting ammonium phosphate and urea together in a molten state. The ammonium phosphate sulphate is transformed to a molten state by generating a lot of heat. Monoammonium phosphates and diammonium phosphates, as well as mixtures of the two and combinations of ammonium nitrate or ammonium sulphate, make up this category of nitrogen phosphorus products.

PHYSICAL PROPERTIES

Chemical formula: NH4)3PO4Density: 1.619 g/cubic cmMolecular Weight/ Molar Mass: 149.09 g/molBoiling Point: 130°CMelting Point: 155 °C (311 °F; 428 K) decomposesOdour: Ammonia odourAppearance: White, tetrahedral crystalsComplexity: 46.5Covalently-Bonded Unit: 3Hydrogen Bond Donor: 3Solubility: Readily soluble in waterSolubility pH: 4 to 4.5

CHEMICAL PROPERTIES

Decomposition of ammonium phosphate produces highly toxic fumes. It produces ammonia and phosphoric acid.

(NH4)3PO4 → 3NH3 + H3PO4

Lead phosphate and ammonium nitrate are formed when ammonium phosphate reacts with lead nitrate.

4(NH4)3PO4 + 3Pb(NO3)4 → Pb3(PO4)4 + 12NH4NO3

USES

Ammonium phosphate is a common term for a number of nitrogen and phosphate-containing fertiliser products.As a source of available P2O5, ammonium phosphates are becoming more essential. Ammonium phosphates have a slightly higher P2O5 content than triple superphosphate.It is most often used as a solid fertiliser, but it can also be used in a solution.They’re used in intumescent paints and mastics, where they function as an acid catalyst.Pentaerythritol is the carbonific part, and melamine is the particular compound, so it’s used in paints.
