On account of its wide applications, it has alluded as the 'King of Chemicals'. Hope this may help :) 23 1 Sulphuric acid also spelt as sulfuric acid or H2SO4 is an odourless, colourless, oily liquid. The forms of phosphorus most readily accessed by plants are orthophosphate ions (H2PO4, HPO42-) whose availability depends on soil pH. Phosphorus trichloride is very toxic and corrosive in nature, hence, it should not come in direct contact with eyes and skin. Hence, phosphorus is released very slowly compared to secondary phosphorus minerals such as calcium, iron, or aluminum phosphates. Ron M. Walls MD, in Rosen's Emergency Medicine: Concepts and Clinical Practice, 2018 Principles. Like oxygen and hydrogen, nitrogen exists in its elemental forms as a diatomic molecule. White phosphorus catches fire spontaneously in air, burning with a white flame and producing clouds of white smoke - a mixture of phosphorus(III) oxide and phosphorus(V) oxide.
