Sometimes the bone glowed in the dark from the accumulated phosphorus. Because mineralization and immobilization processes are biological processes, they are highly influenced by soil moisture, temperature,pH, organic carbon to organic phosphorus ratio of crop residues, microbial population, etc. The major steps involved in the process are: The crucial step is the oxidation of sulfur dioxide, SO2 to sulfur trioxide, SO3. Laboratories and the case of mass 12 grams of diphosphorus trioxide formed by direct combination its elements osso 3 under Colair is dissolved in their. The equation is: 4PCl3 P4 + 6Cl2.
