However, the excess phosphorus is susceptible to loss through runoff and erosion and can promote algal growth in freshwater systems causing the degradation of water quality. Based on the initial reaction mixture, what should be present after the reaction occurs? Although the molecular formula suggests the name tetraphosphorus hexoxide, the name phosphorus trioxide preceded the knowledge of the compound's molecular structure, and its usage continues today. Reactivity Profile. At 40 degree Celsius, it explodes and decomposes into NO and O.

Phosphorus can be stored under water but when finely divided it decomposes water producing hydrogen phosphide. After days of heating up litres of stagnant pee, Hennig managed to isolate a white, waxy solid, which was probably something of a disappointment after his long and olfactorily-challenging work. Another name for it is Oil of Vitriol. The oxidation of sulfur dioxide to sulfur trioxide is an important reaction.
