Phosphoric 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. When all three H⁺ ions are removed, the result is an orthophosphate ion PO₄³⁻, commonly called “phosphate”.
