Phosphoric Acid H3po4

Phosphoric acid

phosphoric acid h3po4 Description:

Phosphoric acid is an inorganic acid. Strictly speaking, the term phosphoric acid refers to all phosphorus based acids. The chemical structural formula of phosphoric acid is H3PO4, but these molecules can recombine to produce a large number of compounds. Any derivative of this acid is called phosphoric acid.

The pure form of phosphoric acid is a white solid at room temperature, but begins to dissolve and form a viscous colorless liquid at a temperature of 42.35 ° C. This compound typically has no water at room temperature, meaning it does not contain any moisture. It has a polar molecular structure, however, this means it is extremely soluble in water.

As a chemical reagent, this acid can often be converted into an aqueous solution. Depending on the amount of acid, it can have a potential hydrogen ion concentration (pH) of 1.08-7.00. 85% of phosphoric acid is corrosive, but can be diluted to become non-toxic.

phosphoric acid h3po4 use:

Phosphoric acid is used in the manufacture of phosphate fertilizer and industrial phosphates, the preparation of phosphating liquid, polishing agent for metal surface phosphating, polishing treatment, the manufacture of calcium phosphate for animal feed and for the toothpaste industry, the manufacture of zinc phosphate for dental fillings adhesive.The pharmaceutical industry is used to manufacture sodium glycerophosphate and iron phosphate, the plastics industry is used as a catalyst for the condensation of phenolic resin, and the daily chemical industry is used as a pH adjustment agent for cosmetics.Edible phosphoric acid is used in the food industry as an acid flavoring agent and a nutrient for yeast.
