Ph of phosphorous acid

The simplest and most commonly encountered of the phosphoric acids is orthophosphoric acid, H3PO4. Indeed, the term phosphoric acid often means this compound specifically (and this is also the current IUPAC nomenclature). Two or more orthophosphoric acid molecules can be joined by condensation into larger molecules by elimination of water. Condensation of a few units yields th… WebThe acid is prepared industrially via a two step process: Firstly, elemental white phosphorus reacts with alkali and alkaline earth hydroxides to give an aqueous solution of hypophosphites: P 4 + 4 OH − + 4 H 2 O → 4 H 2PO− 2 + 2 H 2 Any phosphites produced in this step can be selectively precipitated out by treatment with calcium salts.
