A mineral acid that goes by the formula H3PO4. This formula specifically refers to orthophosphoric acid, but orthophosphoric acids easily combine with themselves to create compounds referred to as phosphoric acids, generally. Typically used as a chemical reagent, the acid is a very polar molecule, meaning it is extremely water soluble. In food usage, the additive is used to acidify foods and ...Chat Online
