  "term": "Arsonous acids",
  "field": "Chemistry",
  "definition": "Organoarsenic(III) compounds of the type RAs(OH)2, formally derived from arsenous acid, As(OH)3, by replacing one hydroxyl group with a hydrocarbyl group, with HAs(OH)2 as parent. In practice they are usually met as their anhydrides RAs=O, such as phenylarsine oxide, which take up water in aqueous solution to give the acid.",
