Phosphoric acid is a colorless, clear and odorless liquid. It is a strong inorganic acid with the chemical formula H3PO4. It can be produced by absorbing phosphorous pentoxide directly in water or through the digestion of phosphate rock with sulfuric acid. The most common form of phosphoric acid is an 85 percent aqueous solution.

Phosphoric acid fuel cells (PAFCs) use liquid phosphoric acid as an electrolyte—the acid is contained in a Teflon-bonded silicon carbide matrix—and porous carbon electrodes containing a platinum catalyst. The electro-chemical reactions that take place in the cell are shown in the diagram to the right.

Nov 08, 2018 · The surprising thing about phosphoric acid is the fact that given how dangerous it is, phosphoric acid is still used in products that we consume, increasing the risk to our internal organs. Exposure to phosphoric acid causes irritation to the throat, nose, and lungs, and is indicated by coughing or wheezing.
Wet-process phosphoric acid is used for fertilizer production. Thermal process phosphoric acid is commonly used in the manufacture of high-grade chemicals, which require a much higher purity. The production of wet-process phosphoric acid generates a considerable quantity of acidic cooling water with high concentrations of phosphorus and fluoride.
Pure phosphoric acid is a crystalline solid (melting point 42.35° C, or 108.2° F); in less concentrated form it is a colourless syrupy liquid. The crude acid is prepared from phosphate rock, while acid of higher purity is made from white phosphorus.
We summarize in this review the recent development of chiral phosphoric acid (CPA)-catalyzed asymmetric dearomatization reactions. A wide array of electron-rich arenes (indoles, phenols, naphthols, benzothiophenes, benzofurans, etc.) and electron-poor arenes (pyridines, quinolines, isoquinolines, etc.) has b
Jun 17, 2015 · Phosphoric acid is a colorless, odorless mineral acid. With an acidic taste and somewhat viscous consistency, phosphoric acid is used in a wide variety of products and industries. Despite its popularity, this chemical can pose some potentially significant health hazards and should be handled with caution.

  • Mar 10, 2016 · Phosphoric acid is used as a rust converter, and one must brush off "accreted" rust ( scale) first. It effectively "Parkerises" the steel. Other Acids convert the rust to soluble salts of iron, and then it can be scrubbed or pressure washed off.
  • Many soft drinks and certain other carbonated soft drinks contain phosphoric acid, which can increase calcium excretion in your urine. ... others show that the right type of soy (with the soy ...
  • True to its name, phosphoric acid is a type of flavor-enhancing acid used to add a "bite" to beverages; it damages teeth chiefly due to its low pH. According to Dr. Dan Peterson at Family Gentle Dental Care, soda with phosphoric acid has pH levels ranging from 2.47 to 3.35, in contrast to the neutral pH of 7.0 found in pure water and a pH of 6 ...
  • The dye reagent of classical Bradford assay contains 8.50% (w/v) phosphoric acid, which is an important factor relating to the color yield of the assay. In this study, the phosphoric acid content in dye reagent was increased to 9.35% (w/v), 10.20% (w/v), and 11.05% (w/v) to evaluate the changes of interference and the effects of lysis buffer on ...
  • Phosphoric Acid is used in the formulation of a wide variety of product types, including bath products, cleansing products, fragrances, hair care products, hair dyes and colors, makeup, mouthwashes, nail products and skin care products.

Mar 15, 2010 · Phosphoric acid may work as a homeopathic remedy for varying degrees and different types of diarrhea. It may help with a temporary type of diarrhea that is often associated with an illness, or may help if diarrhea is an actual side effect of a digestive disorder.

Phosphoric Acid (40% Solution) Hand Drum Pumps 16 products Hand drum pumps are manually powered devices operated by a crank, lever, or other mechanism to draw fluids out of a container. Phosphoric Acid (PA) has a typical concentration of 75, 80 and 85%. One of the drawbacks of phosphoric acid is that, as its concentration increases, its freezing temperature also increases. As a result, the main strength of acid used for various applications remains 75%wt which freezes at -18C; as it is easier to handle and store during cold ...

The phosphoric acid produced by either the wet or dry process is frequently heated, driving off water and producing a superphosphoric acid. The phosphate concentration in superphosphoric acid usually varies from 72 to 76 percent. The P in this acid is present as both orthophosphate and polyphosphate.
