commentaire Explanation: Il me semble bizarre car votre phrase n'apparait en google, je ne trouve que l'acide arsénieux, pas "l'hydrogene arsénieux" -------------------------------------------------- Note added at 1 hr (2008-07-12 12:17:12 GMT) -------------------------------------------------- Tiene algo que ver con "aresenious/arseniuretted hydrogen" en inglés? In the Marsh test the solution containing the arsenious compounds is mixed with pure hydrochloric acid and placed in an apparatus in which hydrogen is generated from pure zinc and pure sulphuric acid. The arseniuretted hydrogen produced is passed through a tube containing lead acetate paper and soda-lime, and finally through a narrow glass tube, constricted at various points, and heated by a very small flame. As the arseniuretted hydrogen passes over the heated portion it is decomposed and a black deposit formed. Instead of heating the tube, the gas may be ignited at the mouth of the tube and a cold surface of porcelain or platinum placed in the flame, when a black deposit is formed on the surface. This may be distinguished from the similar antimony deposit by its ready solubility in a solution of sodium hypochlorite. A blank experiment should always be carried out in testing for small quantities of arsenic, to ensure that the materials used are quite free from traces of arsenic. It is to be noted that the presence of nitric acid interferes with the Marsh test; and also that if the arsenic is present as an arsenic compound it must be reduced to the arsenious condition by the action of sulphurous acid. Arsenic compounds can be detected in the dry way by heating in a tube with a mixture of sodium carbonate and charcoal when a deposit of black amorphous arsenic is produced on the cool part of the tube, or by conversion of the compound into the trioxide and heating with dry sodium acetate when the offensive odour of the extremely poisonous cacodyl oxide is produced. In the wet way, arsenious oxide and arsenites, acidified with hydrochloric acid, give a yellow precipitate of arsenic trisulphide on the addition of sulphuretted hydrogen; this precipitate is soluble in solutions of the alkaline hydroxides, ammonium carbonate and yellow ammonium sulphide. Under like conditions arsenates only give a precipitate on long-continued boiling. -------------------------------------------------- Note added at 1 hr (2008-07-12 12:18:10 GMT) -------------------------------------------------- Sí, podrá ser "arsenious hydrogen" en inglés -------------------------------------------------- Note added at 1 hr (2008-07-12 12:19:15 GMT) -------------------------------------------------- Technical English - Spanish Vocabulary - [ Translate this page ] Arsenious, arsenioso; arsenious oxyde, óxido arsenioso.

hidrógeno arsenioso Explanation: Creo que esto puede servirte, suerte! "Debe tomar precauciones, pues se desprenden gases tóxicos: el vapor de mercurio y, sobre todo, el hidrógeno arsenioso." http://elretornodelosbrujosde.blog.com/ En el libro Materia Médica Pura, de Samuel Hannemann también es citado el hidrógeno arsenioso, como siendo un gas tóxico: "Gehlen murió por inhalaciones de hidrógeno arsenioso." http://books.google.com.br/books?id=jetvfcnCnsYC&pg=PA176&lp... |

arsina / hidruro de arsénico Explanation: La arsina o hidruro de arsénico (AsH3) es un compuesto inorgánico gaseoso a temperatura ambiente, es inflamable y altamente tóxico, constituido de hidrógeno y arsénico. La arsina es más pesada que el aire, soluble en agua, incolora, y con un olor suave a ajo que sólo es percibido cuando se encuentra en altas concentraciones. |
