Phosphotungstic acid (PTA), tungstophosphoric acid (TPA), is a heteropoly acid with the chemical formula H3PW12O40nH2O. It is normally isolated as the n = 24 hydrate but can be desiccated to the hexahydrate. EPTA is the name of ethanolic phosphotungstic acid, its alcohol solution used in biology.
convenient one-tube method for serum uric acid is described which employs a single addition of phosphotungstic acid. Serum proteins are precipitated and sufficient phospho-18-tungstic acid remains in the supernatant solution for oxidation of uric acid following alkalinization with sodium carbonate.
hosphotungstic acid (PTA), tungstophosphoric acid (TPA), is a heteropoly acid with the chemical formula H3PW12O40nH2O. ... It has the appearance of small, colorless-grayish or slightly yellow-green crystals, with melting point 89 °C (24 H2O hydrate). It is odorless and soluble in water
Too much phosphorus can decrease the amount of calcium in your body, leading to bone loss. It can also impair your body's ability to use other minerals, such as iron, zinc, and magnesium. Phosphoric acid is dangerous if you come into contact with it as a chemical substance.
