High Quality Food Grade 85% Phosphoric 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.

Application:
The dominant use of phosphoric acid is for fertilizers, consuming approximately 90% of production.Food-grade phosphoric acid (additive E338) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. Soft drinks containing phosphoric acid, which would include Coca-Cola, are sometimes called phosphate sodas or phosphates. Phosphoric acid in soft drinks has the potential to cause dental erosion. Phosphoric acid also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.
Specific applications of phosphoric acid include:
• In anti-rust treatment by phosphate conversion coating or passivation
• As an external standard for phosphorus-31 nuclear magnetic resonance.
• In phosphoric acid fuel cells.
• In activated carbon production.
• In compound semiconductor processing, to etch Indium arsenide selectively with respect to indium phosphide.
• In microfabrication to etch silicon nitride selectively with respect to silicon dioxide.
• As a pH adjuster in cosmetics and skin-care products.
• As a sanitizing agent in the dairy, food, and brewing industries.
