Question

calculate it for PCl3, and P2O5 ?​

Answer 1

Answer:

4 NH₃ + 3 H₂O + P₂O₅ → 2 (NH₄)₂HPO₄

2 moles of Diammonium phosphate is synthesized from 1 mole of Phophorous pentoxide.

1 mole of Diammonium phosphate can be synthesized from 1/2 mole of Phophorous pentoxide.

So, 1 mole Diammonium phosphate contains 1/2 mole of Phosphorous pentoxide.

132 gms of diammonium phosphate contains 71 gms of phosphorous pentoxide.

100 gms of diammonium phosphate contains 71 × 100 / 132 gms

                                                                = 53.787 gms of P₂O₅

Hence, 53.8 % (approximately) of P₂O₅ is present in (NH₄)₂PO₄

Answer 2

hosphorus trichloride is a chemical compound of phosphorus and chlorine, having the chemical formula PCl3. It is a toxic and volatile liquid which reacts violently with water to release HCl gas. It has a trigonal pyramidal shape, owing to the lone pairs on the phosphorus. It is an important industrial chemical, being used for the manufacture of phosphites and other organophosphorus compounds for a wide variety of applications. It has a 31P NMR signal at around +220 ppm with reference to a phosphoric acid standard.Phosphorus pentoxide is a white, microcrystalline, light weight powder which is produced by the combustion of elemental phosphorus in an excess of oxygen. Phosphorus pentoxide is the anhydride of orthophosphoric acid, H3PO4. It is very hygroscopic and is converted by water to H3PO4 via intermediates.
