The phosphorus atom in a phosphoric acid molecule is bonded with 4 oxygen atoms, one with a double bond and the other three with single bonds. Phosphonic acid is a phosphorus oxoacid that consists of a single pentavalent phosphorus covalently bound via single bonds to a single hydrogen and two hydroxy groups and via a double bond to an oxygen. Here’s a 2D version of the structure, for easier comprehension. It is a colorless low-melting compound, which is soluble in water, dioxane, and alcohols. Only the reduced phosphorus compounds are spelled with an "ous" ending. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. It derives from a phosphonic acid. It is used in the production of basic lead phosphonate PVC stabilizer, aminomethylene phosphonic acid and hydroxyethane diphosphonic acid. Phosphonic acids can replace the two bridging atoms by donation of a proton to form phosphoric acid and bonding across the vacated four valent metal atoms. Phosphorous acid slowly oxidizes in air to phosphoric acid.[3]. This species exists in equilibrium with an extremely minor tautomer P(OH)3. KNOW THE PRODUCT PHOSPHONIC ACID.
