Sentence Examples

  • The solid substance is, however, only exceptionally met with, as it at once dissolves in the mist of sulphuric acid floating in the chamber and forms" nitrous vitriol."Wherever this nitrous vitriol comes into contact with liquid water (not steam), which is also present in the chamber in the shape of mist, and practically as dilute sulphuric acid, it is decomposed into sulphuric and nitrous acid, thus: SO 2 (OH)(ONO) + H 2 O = H 2 SO 4 + HN02.
  • The first step towards securing this requirement was taken as early as 1827 by Gay-Lussac, who discovered that the nitrous fumes, otherwise carried away from the lead chambers by the waste atmospheric nitrogen and oxygen, could be retained by bringing the gases into contact with moderately strong sulphuric acid, the result being the formation of nitroso-sulphuric acid: 2H 2 SO 4 + N203 = 2S0 2 (OH) (ONO) + H 2 O, and the latter remaining dissolved in sulphuric acid as "nitrous vitriol."
  • The reaction is then: 2SO 2 (OH) (ONO) + SO 2 + 2H 2 O = 3H 2 SO 4 + 2NO; that is to say, all the "nitre" is returned to the chambers in the shape of NO; the sulphuric acid employed in the Gay-Lussac process is not merely recovered, but an additional quantity is formed from fresh S02; as the heat of the burner-gases also comes into play, much water is evaporated, which supplies part of the steam required for the working of the chambers; and the acid issues from the apparatus in a "denitrated" and sufficiently concentrated state (78 to 80% H2S04) to be used over again for absorbing nitrous vapours or any other purpose desired.
  • 17-48) this is suggested by a comparison with Luke itself, and there are ono or two others where from the character of the matter it seems not improbable, especially vi.
