Oxides of Phosphorus | Tricks and Techniques | IIT Jee Mains, Advance | BITSAT | NEET & AIIMS

Oxides of Phosphorus is always been an important topic for Jee and medical entrance exam so we are providing you some tricks and tech for these beautiful compounds. Phosphorus forms two common oxides, phosphorus(III) oxide (or tetraphosphorus hexoxide), P4O6, and phosphorus(V) oxide (or tetraphosphorus decaoxide), P4O10. Both oxides have a structure based on the tetrahedral structure of elemental white phosphorus. Phosphorus(III) oxide is a white crystalline solid that smells like garlic and has a poisonous vapour. It oxidizes slowly in air and inflames when heated to 70 °C (158 °F), forming P4O10. It is the acid anhydride of phosphorous acid, H3PO3, that is produced as P4O6 dissolves slowly in cold water. Phosphorus(V) oxide is a white flocculent powder that can be prepared by heating elemental phosphorus in excess oxygen. It is very stable and is a poor oxidizing agent. The P4O10 molecule is the acid anhydride of orthophosphoric acid, H3PO4. When P4O10 is dropped into water, it makes a hissing sound, heat is liberated, and the acid is formed. Because of its great affinity for water, P4O10 is used extensively as a drying agent for gases and for removing water from many compounds. P4O10 + 6H2O → 4H3PO4 We hope you all will enjoy the lecture.
