The earHest preparations of phosphorus involved concentrating urine, followed by distillation after . Others who mixed the chemicals as well as those who boxed up the matches were also exposed to high levels of phosphorus. This pool consists of adsorbed phosphorus, secondary phosphate minerals, and organic phosphorus that mineralizes easily. Soils with greater clay content have higher adsorption capacity than coarse textured sandy soils. A prefix in the name of a binary molecular compound tells how many atoms of an element are present in each molecule of the compound. It is the acid anhydride of phosphorous acid, H 3 PO 3, that is produced as P 4 O 6 dissolves slowly in cold water. It is inflammable and can be ignited at 45C. Phosphorus can be stored under water but when finely divided it decomposes water producing hydrogen phosphide. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Structure: The exact structure of red phosphorus is not yet known.
