  Sulphuric  \Sul*phu"ric\,  a.  [Cf.  F.  sulfurique.] 
  1.  Of  or  pertaining  to  sulphur;  as  a  sulphuric  smell. 
 
  2.  (Chem.)  Derived  from  or  containing,  sulphur;

  {Sulphuric  acid}. 
  a  Sulphur  trioxide  (see  under  {Sulphur});  --  formerly  so 
  called  on  the  dualistic  theory  of  salts.  [Obs.] 
  b  A  heavy,  corrosive,  oily  liquid,  {H2SO4},  colorless 
  when  pure,  but  usually  yellowish  or  brownish,  produced 
  by  the  combined  action  of  sulphur  dioxide,  oxygen 
  (from  the  air),  steam,  and  nitric  fumes.  It  attacks 
  and  dissolves  many  metals  and  other  intractable 
  substances,  sets  free  most  acids  from  their  salts,  and 
  is  used  in  the  manufacture  of  hydrochloric  and  nitric 
  acids,  of  soda,  of  bleaching  powders,  etc  It  is  also 
  powerful  dehydrating  agent,  having  a  strong  affinity 
  for  water,  and  eating  and  corroding  paper,  wood, 
  clothing,  etc  It  is  thus  used  in  the  manufacture  of 
  ether,  of  imitation  parchment,  and  of  nitroglycerin. 
  It  is  also  used  in  etching  iron,  in  removing  iron 
  scale  from  forgings,  in  petroleum  refining,  etc.,  and 
  in  general  its  manufacture  is  the  most  important  and 
  fundamental  of  all  the  chemical  industries.  Formerly 
  called  {vitriolic  acid},  and  now  popularly  {vitriol}, 
  and  {oil  of  vitriol}. 
 
  {Fuming  sulphuric  acid},  or  {Nordhausen  sulphuric  acid}.  See 
  {Disulphuric  acid},  under  {Disulphuric}. 
 
  {Sulphuric  anhydride},  sulphur  trioxide.  See  under  {Sulphur}. 
 
 
  {Sulphuric  ether},  common  an[ae]sthetic  ether;  --  so  called 
  because  made  by  the  catalytic  action  of  sulphuric  acid  on 
  alcohol.  See  {Ether},  3
