Hydrophosphoric Acid H3P Molar Mass, Molecular Weight. This is an exception. The electronic structure of hypophosphorous acid is such that it has only one hydrogen atom bound to oxygen, and it is thus a monoprotic oxyacid. For example, following data is given regarding the structure of pyrophosphorus acid in my textbook, which is not consistent with the number of oxygen atoms. In hypophosphoric acid the phosphorus atoms are identical and joined directly with a P−P bond. Disclosed is a method of making hypophosphorous acid from sodium hypophosphite by performing electrodialytic water splitting upon an aqueous solution of sodium hypophosphite.
