Orthophosphoric Acid

Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H3PO4. It is normally encountered as a colorless, syrup of 85% concentration in water. The pure compound is a colorless solid.Phosphoric acid is commonly encountered in chemical laboratories as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. Although phosphoric acid does not meet the strict definition of a strong acid, the 85% solution can still severely irritate the skin and damage the eyes.

Molecular formula:H3PO4
Molecular weight:97.99
Content:75%,81%,85%.
Properties: Colorless transparent viscous liquid. It is odorless, very sour, melting point 42.35 C, soluble in water, soluble in ethanol. It can stimulate skin inflammation, destroy body tissues, and has hygroscopicity.

Application

Industry	Phosphoric Acidused in removing dust from the metal surfaces. Used as rust converter by bringing it in direct contact with a rusted iron, or steel tools and other surfaces that are rusted. It is helpful in cleaning the mineral deposits, cement nous smears and hard water stains.
Food	Used to acidify the foods and beverages such as colas.
Medicine	Phosphoric Acid is an important ingredient in over the counter medications to combat nausea.
Dentistry	Phosphoric Acid is mixed with zinc powder and forms zinc phosphate, and it is useful in temporary dental cement. In orthodontics, zinc is used as an etching solution to help clean and roughen the surface of teeth.
Fertilizer	Used as reaction fertilizer in the soil around a granule acidification is generated that improves the utilization of phosphorus applied and available in the rhizosphere. Due to its nitrogen content (present as ammo nia), it is good for crops that require these nutrients in its initial phase
