Phosphat anion säure

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. WebPhosphinates or hypophosphites are a class of phosphorus compounds conceptually based on the structure of hypophosphorous acid. IUPAC prefers the term phosphinate in all cases, however in practice hypophosphite is usually used to describe inorganic species (e.g. sodium hypophosphite ), while phosphinate typically refers to organophosphorus species.
