  "term": "Arsonic acids",
  "field": "Chemistry",
  "definition": "Organoarsenic(V) acids of the type RAs(=O)(OH)2, in which arsenic carries one hydrocarbyl group, one oxo group, and two hydroxyl groups, with HAs(=O)(OH)2 as parent. They are the arsenic analogues of phosphonic acids and are diprotic, with a first pKa typically near 3 to 4 and a second near 8 to 9. Phenylarsonic acid and the livestock feed additive roxarsone are examples.",
