Phosphorus pentoxide (P 4 O 10) is a white powder and very deliquescent (forming phosphoric acid), and is used as a dehydrating agent. Allotropes of phosphorus. Phosphorus occurs in several allotropic forms, the most common of which are white phosphorus and red phosphorus (Fig 2). The former is a waxy, yellowishwhite, very inflammable, and ...
What are the products obtained in the reaction of white phosphorus with aqueous sodium hydroxide? I know one will be phosphine (ce{PH3}). How can we find the oxidation state of phosphorus in the other product? Thanks for help in advance. inorganicchemistry redox oxidationstate. Share. Improve this question.

· Residual phosphoric acid content is between about % by weight and about % by weight. The molar ratio of phosphorous to phosphoric acid in the phosphorous acid product is at least about 50, typically between about 90 and about 100. The substantially waterimmiscible organic phase of the hydrolysis reaction mixture contains phosphate esters to the .
· White phosphorus is used mainly for producing phosphoric acid and other chemicals. These chemicals are used to make fertilisers, additives in foods and drinks, cleaning compounds, and other products. Small amounts of white phosphorus have been used as rat and roach poisons and in fireworks. In the past, white phosphorus was used to make matches, but another chemical with .
It is prepared by heating white phosphorus under high pressure. Phosphoric acid (H3PO4) is a basic chemical used in drugs, animal feed, and fertilizers. According to the Bureau of Mines, nearly 93 percent of the phosphate rock sold or used in the in 1991 was for the manufacture of wetprocess phosphoric acid, single superphosphate,

White phosphorus causes severely painful, partial (second degree) to full thickness (third degree) burns, which have a characteristic yellow color and garliclike odor. Smoke may release from the burn site from the continued burning of white phosphorus or the formation of phosphoric acid.
Phosphoric acid, also known as orthophosphoric acid, is a mineral acid with the chemical formula H3PO4. Pure, anhydrous phosphoric acid is a white solid which melts at 42 degrees Celsius to form a viscous liquid. Commonly used phosphoric acid is an aqueous solution of 7585% H3PO4 which is generally produced by two different processes: wet process and thermal .
A better method is that recommended by Davy, namely, by the hydrolysis of phosphorus trichloride. Some white phosphorus is placed in a deep cylinder and covered with water. The element is melted and chlorine is passed in through a tube which dips well into the phosphorus. Large quantities may be quickly obtained by this method, but the product contains phosphoric acid. Regulated action of PCl ...
white phosphorus may be transformed not only to phosphoric acid, but also to phosphine in the body (ATSDR, 1997). Phosphorus pentoxide would not be expected to undergo transformation to phosphine in the body. In addition, some of the characteristic effects of white phosphorus exposure by the inhalation, oral and dermal routes have not been seen ...
