Description
Phosphoric acid or phosphate, chemical formula H3PO4, molecular weight of 97.9724, is a kind of common inorganic acid, is in strong acid. By ten oxidation four phosphorus soluble in hot water can be obtained. The use of sulfuric acid in the process of the phosphoric acid industry is a. Phosphoric acid easily deliquescent in the air. The heat can be obtained by the loss of coke, and then the further loss of water is obtained. Phosphoric acid is mainly used in the pharmaceutical, food, fertilizer and other industries, also can be used as chemical reagents.

Application of agricultural production is an important editor: phosphate fertilizer (calcium superphosphate, potassium dihydrogen phosphate) of raw materials, but also the production of feed nutrients (
The raw material of calcium dihydrogen phosphate).
Industry: phosphoric acid is an important chemical raw material, the main role is as follows:
Treatment of metal surface, the metal surface of the formation of insoluble phosphate film, in order to protect the metal from corrosion.
And nitric acid mixture as a chemical polishing agent, to improve the surface finish of the metal.
Raw phosphate for producing washing products and pesticide.
The production of flame retardant materials.
Food: phosphoric acid is one of the food additives, in the food as a sour agent, yeast nutrients, Coca-Cola contains phosphoric acid. Phosphate is also
Important food additives can be used as nutritional enhancer.
Medicine: phosphoric acid can be used to produce drugs such as phosphorus, sodium glycerophosphate etc..
