A phosphite anion or phosphite in inorganic chemistry usually refers to [HPO3] but includes [H2PO3] ([HPO2(OH)] ). These anions are the conjugate bases of phosphorous acid (H3PO3). The corresponding salts, e.g. sodium phosphite (Na2HPO3) are reducing in character. See more The IUPAC recommended name for phosphorous acid is phosphonic acid. Correspondingly, the IUPAC-recommended name for the HPO 3 ion is phosphonate. In the US the IUPAC naming conventions for inorganic … See more Acid or hydrogen phosphites are called hydrogenphosphonates or acid phosphites. IUPAC recommends the name hydrogenphosphonates). They are anions HP(O)2OH . Aypical derivative is the salt [NH4][HP(O)2OH]. Many related salts are known, e.g., … See more In contrast to the paucity of evidence for PO 3, the corresponding arsenic ion, ortho-arsenite, AsO 3 is known. An example is Ag3AsO3 as well as the polymeric meta-arsenite (AsO 2) n. … See more • Hypophosphite – H 2PO 2 • Organophosphorus • Phosphine – PH3 and the organic phosphines PR3 See more From the commercial perspective, the most important phosphite salt is basic lead phosphite. Many salts containing the phosphite ion have been investigated structurally, these … See more Pyrophosphites (diphosphites) can be produced by gently heating acid phosphites under reduced pressure. They contain the ion H 2P 2O 5, which can be formulated [HP(O)2O−P(O)2H] . See more Inorganic phosphites (containing HPO 3) have been applied to crops to combat fungus-like pathogens of the order oomycetes (water molds).
