Phosphoric Acid

Phosphoric Acid, also known as oPhosphoric Acid 85% or Phosphoric Acid 85% Food Grade, is a Acid Product with the chemical formula H3PO4. The pure compound is a colorless solid.

All three hydrogens are acidic to varying degrees and can be lost from the molecule as H+ ions (protons). When all three H+ ions are removed, the result is an orthophosphate ion Pvc Resin PO43−, commonly called "phosphate". Removal of one or two protons gives dihydrogen phosphate ion H2PO−4, and the hydrogen phosphate ion HPO2−4, Ethylene-Vinyl Acetate respectively. Orthophosphoric acid also forms esters, called organophosphates.

Phosphoric Acid Food Grade 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.

The name "orthophosphoric acid" can be used to distinguish this specific acid from other "Phosphoric Acid 75%", such as pyrophosphoric acid. Nevertheless, the term "phosphoric acid" often means this specific compound; and that is the current IUPAC nomenclature.
