Phosphoric acid is a mineral acid with the chemical formula H₃PO₄. It is a clear, odorless liquid that is highly soluble in water. Phosphoric acid is classified as a weak acid. It exists in solutions as a mixture of orthophosphoric acid molecules (H₃PO₄), dihydrogen phosphate ions (H₂PO₄⁻), and hydrogen phosphate ions (HPO₄²⁻). The acidity of phosphoric acid is due to the release of hydrogen ions (H⁺) when it dissolves in water.
Benefits
