Of considerable economic significance is phosphineor hydrogen phosphide, PH 3. This gaseous compound is produced either by the action of a strong base or hot water on white phosphorus or by the hydrolysis of a metal phosphide. Phosphine is used mainly as a starting material in the synthesis of various organic phosphorus compoundsas a doping agent for solid-state electronics components, and as a fumigant. Among the most commercially important phosphorus compounds are the oxides and acids.
Much of the industrially produced white phosphorus is burned to form phosphorus pentoxideP 4 O Sometimes called phosphoric anhydride, or diphosphorus pentoxide, this compound can be obtained in the form of a soft white powder or colourless crystalline solid. It is widely used in chemical analysis as a dehydrating agent and in organic synthesis as a condensing typicallh.
Such salts are used as leavening agents in baking, as how to clear toolbar history internet explorer in toothpaste, and sometimes as additives to detergents.
Another saltprepared by the action of phosphoric acid on phosphate rockis calcium dihydrogen phosphate, or superphosphate, Ca H 2 PO 4 2the most widely used phosphate fertilizer. These halides are used to synthesize organic phosphorus chemicals. Phosphorus reacts with sulfur to form several sulfides that are used in the manufacture of organic chemicals and matches.
It reacts with many metals phosphorus is typically found in what ionic form metalloids to form phosphides. Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes. The phosphoglycerides, for example, are required for fermentation.
The adenosine phosphates are essential in photosynthesis and for muscle action; adenosine triphosphate ATP plays a central role in metabolism and is found in the cells of all living things. Industrially important organic phosphorus compounds include plasticizers and gasoline additives. Certain highly toxic forms are employed in insecticides of the parathion type.
Phosphoruw organic derivatives of phosphorus have been used as nerve gasa key weapon of chemical warfare. Elemental phosphorus can be detected by its phosphorescence. It can also be converted to phosphine with boiling sodium hydroxide solution or with zinc and sulfuric acid ; the phosphine is identified by means of test paper containing either silver nitrate or mercuric chloride, both of which are reduced to the free metal by phosphine, thereby darkening the paper.
Phosphorus vapour also readily darkens silver nitrate test paper. Phosphorus is determined quantitatively by oxidation to phosphate, followed by any of several standard procedures. Phosphate, for example, may be precipitated as the magnesium ammonium salt, MgNH 4 PO 4converted by ignition to magnesium pyrophosphate, Mg 2 P 2 O 7and weighed.
Alternatively, phosphate may be precipitated as ammonium phosphomolybdate; this can be weighed as such, converted to magnesium pyrophosphate and weighed, or titrated directly with sodium hydroxide solution. Iw is phoaphorus important constituent of bones and teethand it is essential to i growth of living organisms.
In organisms the element usually appears as phosphate. In its other forms phosphorus is likely to prove very toxic. Phosphine is extremely toxic, as are its organic derivatives. Some of the most toxic substances known to man, collectively termed nerve gasare organic derivatives of phosphorus. The geneswhich direct heredity and other cellular functions and are found in the nucleus of each cell, are molecules of DNA deoxyribonucleic acidwhich all contain phosphorus. Cells store the energy obtained from nutrients in molecules of adenosine triphosphate ATP.

Adenosine triphosphate, or ATP, is the primary carrier of energy in cells. The water-mediated reaction known as hydrolysis releases energy from the chemical bonds in ATP to fuel cellular processes.

The elements share certain general similarities in chemical behaviour, though they are clearly differentiated from one another chemically, and these similarities reflect common….
The phosphorus content depends on the ore used, since phosphorus is not removed in the blast-furnace process, whereas sulfur is usually picked up during iron making…. The mother has some phosphorus reserve but must acquire enough from her diet to supply her own tissues and those of the fetus.

Jan 19, · Phosphorus is typically found in what ionic form? In concern to the Phosphorus Cycle. Trying to take notes for a test and I cant find it in this stupid book! Apr 05, · Hence, phosphorus is released very slowly compared to secondary phosphorus minerals such as calcium, iron, or aluminum phosphates. Precipitation on the other hand is a process by which metal ions such as Al 3+ and Fe 3+ (these ions are dominant in acidic soils) and Ca 2+ (dominant in calcareous soils) react with phosphate ions present in the soil solution to form minerals such as Al-, . Principal compounds Phosphorus is used almost entirely in the form of compounds, usually in the oxidation states of +3, +5, and ?3. Unlike nitrogen and various other members of the family, phosphorus tends to exhibit a preference for the +5 state. Of considerable economic significance is phosphine, or hydrogen phosphide, PH 3.
This extremely strong bond is the driving force behind several reactions involving phosphorus. For example, the reaction of PCl 5 with water to become H 3 PO 4 allows it to serve as a drying agent, or dessicant, with the P-O bond formation as the driving force. The oxygen-phosphorus bond also prohibits phosphorus from being observed in its elemental state in nature. It is always found as an oxide. The majority of phosphorus-containing compounds are produced for use as fertilizers.
For this purpose, phosphate-containing minerals are converted to phosphoric acid. Two distinct routes are employed; the main one is treatment of phosphate minerals with sulfuric acid. The other process utilizes white phosphorus, which may be produced by reaction and distillation from very low-grade phosphate sources. The white phosphorus is then oxidized to phosphoric acid and finally neutralized with a base to yield phosphate salts.
Phosphoric acid obtained from white phosphorus is relatively pure and is the main source of phosphates used in detergents and other non-fertilizer applications. As such, phosphate salts are used as fertilizers to aid plant growth. Living cells also use phosphate to transport cellular energy in the form of adenosine triphosphate ATP. Nearly every cellular process that uses energy obtains it in the form of ATP. ATP is also important for phosphorylation, a key regulatory and signal-transducing event in cells.
Phospholipids are the main structural components of all cellular membranes and consist of a long alkyl chain terminating in a phosphate group. Calcium phosphate salts help to harden bones. Living cells are defined by a membrane that separates it from its surroundings. Biological membranes are made from a phospholipid matrix and proteins, typically in the form of a bilayer. Phospholipids are derived from glycerol, such that two of the glycerol hydroxyl OH groups have been replaced with fatty acids to form ester linkages, and the third hydroxyl group has been replaced with a phosphate group.
Phosphorous oxoacids are extensive, often commercially important, and sometimes structurally complicated. They all have acidic protons bound to oxygen atoms, and some have nonacidic protons that are bonded directly to phosphorus.
Although many oxoacids of phosphorus are formed, only nine are important, and three are crucial: hypophosphorous acid, phosphorous acid, and phosphoric acid. They are widely used commercially. For example, it is the precursor to triphenylphosphine:. Treatment of phosphorus trihalides with alcohols and phenols yields phosphites, such as triphenylphosphite:.
There are several other phosphorus V compounds. The most prevalent compounds of phosphorus are derivatives of phosphate PO 4 3- , a tetrahedral anion. Phosphate is the conjugate base of phosphoric acid, which is produced on a massive scale for use in fertilizers. Since it is triprotic, phosphoric acid converts stepwise to three conjugate bases:.
