      The acid is prepared industrially via a two step process. Hypophosphite salts of the alkali and alkaline earth metals result from treatment of white phosphorus with hot aqueous solution of the appropriate hydroxide, e.g. Ca(OH)2.
      P4 + 3OH− + 3H2O → 3H2PO2− + PH3
      The free acid may be prepared by the action of a strong acid on these hypophosphite salts.
      H2PO2− + H+ → H3PO2
      Alternatively, H3PO2 arises by the oxidation of phosphine with iodine in water.
      PH3 + 2I2 + 2H2O → H3PO2 + 4I− + 4H+
      HPA is usually supplied as a 50% aqueous solution.


      Hope this helps.
