Hypophosphoric Acid Formula: Hypophosphoric acid formula is H4P2O6. It is characterized by a +4 oxidation state of phosphorus and It is found in a dihydrate state, H4P2O6.2H2O, as a solid. Hypophosphoric acid can be produced through the reaction of red phosphorus with sodium chlorite at room temperature.
Hypophosphoric acid, with the chemical formula H4P2O6, exhibits acidic properties and is characterized by the presence of phosphorus in a specific oxidation state. This compound comprises four hydrogen, two phosphorus, and six oxygen atoms. In its structure, a P-P bond exists, with each phosphorus atom forming two P-OH bonds and one P-O bond.
The P-P bond has a length of 219 picometers (pm), while the P-OH bond measures 159 pm, and the P-O bond is 151 pm long. An oxygen bridge connects one phosphorus atom to another, leading to the formation of phosphoric acid. In its solid state hypophosphoric acid is present as the dihydrate.
The chemical formula for Hypophosphoric acid is H4P2O6, and it typically exists as the dihydrate, H4P2O6.2H2O, also known as di-phosphoric acid

Hypophosphoric Acid Formula Structure
The Hypophosphoric acid formula is H4P2O6. Its structure consists of two phosphorus atoms, connected by a P-P bond, with each phosphorus atom bonded to two hydroxyl (OH) groups and one oxygen atom (O).
Hypophosphoric Acid Oxidation State
The oxidation state of phosphorus in Hypophosphoric acid (H4P2O6) is +5.
Hypophosphoric Acid Basicity
The H4P2O6 structure features four P-OH bonds, which results in four acidic hydrogens. Consequently, the basicity of hypophosphoric acid is 4.
Hypophosphoric Acid Preparation
Hypophosphoric acid can be produced by combining red phosphorus with sodium chlorite at room temperature. Alternatively, when white phosphorus is partially dissolved in water. It undergoes oxidation in the presence of air. resulting in a mixture of Hypophosphoric acid, phosphorous acid, and phosphoric acid. The chemical equation for this reaction is:
2P + 4NaOCl2 + 2H2O → H4P2O6 + 2NaCl
There is no P-H bonds, which means it cannot work as a reducing agent. It has four acidic hydrogens and includes a P-P bond in its structure.
