Reactive phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosph… WebApr 9, 2024 · Reactions between red phosphorus (P red) and potassium ethoxide in various organic solvents under reflux convert this rather inert form of the element to soluble …

WebFeb 11, 2024 · Reactive phosphorus is the phosphorus associated with the test for orthophosphate. It consists mostly of orthophosphate but includes a small fraction of other forms. Soluble reactive phosphorus is a measure of orthophosphate, the filterable (soluble, inorganic) fraction of phosphorus, the form directly taken up by plant cells. WebIn contrast, red phosphorus is insoluble and relatively inert, although large quantities of the usual commercial form can ignite spontaneously in air and react with water to form …

WebTotal phosphorus analyses measure every atom of phosphorus, whether in the liquid or solid fraction. Reactive phosphorus generally measures all orthophosphate, as well as some simple organic and polyphosphate. Samples can be filtered or allowed to settle so that aliquots for soluble fractions can be analyzed. Phosphorus commonly is reported as ...
