Phosphoric acid - Wikipedia

Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H 3PO 4. 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 PO4 , commonly called "phosphate". Removal of one or two protons gives dihydr
