Phosphorus is a fascinating element that occurs in at least three very different forms. If left exposed to the air, it catches fire on its own. It also glows in the dark. Today, its most important use is in the manufacture of phosphoric acid (H 3 PO 4 ).
Red phosphorus is used in safety matches, fireworks, smoke bombs and pesticides. Black phosphorus is also formed by heating white phosphorus, but a mercury catalyst and a seed crystal of black phosphorus are required. Black phosphorus is the least reactive form of phosphorus and has no significant commercial uses.Phosphoric acid (H 3 PO 4) is used in soft drinks and to create many phosphate compounds, such as triple superphosphate fertilizer (Ca(H 2 PO 4) 2 Â·H 2 O).Trisodium phosphate (Na 3 PO 4) is used as a cleaning agent and as a water softener.ed phosphorus is used in safety matches, fireworks, smoke bombs and pesticides.
