  "id": "MLC-T-CHM-008784",
  "term": "Phosphonous acids",
  "field": "Chemistry",
  "definition": "Compounds of the form R-P(OH)2, derived from the parent HP(OH)2, in which a trivalent phosphorus atom bears one organic group and two hydroxyl groups. They exist mainly as the tautomeric H-phosphinic acids, R-P(=O)(H)OH, which have a P-H bond and are monobasic, and they are readily oxidized to phosphonic acids, RP(=O)(OH)2.",
