  Saleratus  \Sal`e*ra"tus\,  n.  [NL.  sal  a["e]ratus;  --  so  called 
  because  it  is  a  source  of  fixed  air  (carbon  dioxide).  See 
  {Sal},  and  and  {A["e]rated}.]  (Old  Chem.) 
  A["e]rated  salt;  a  white  crystalline  substance  having  an 
  alkaline  taste  and  reaction,  consisting  of  sodium  bicarbonate 
  (see  under  {Sodium}.)  It  is  largely  used  in  cooking,  with 
  sour  milk  (lactic  acid)  or  cream  of  tartar  as  a  substitute 
  for  yeast.  It  is  also  an  ingredient  of  most  baking  powders, 
  and  is  used  in  the  preparation  of  effervescing  drinks. 
 
  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Sodium  \So"di*um\,  n.  [NL.,  fr.E.  soda.]  (Chem.) 
  A  common  metallic  element  of  the  alkali  group  in  nature 
  always  occuring  combined,  as  in  common  salt,  in  albite,  etc 
  It  is  isolated  as  a  soft,  waxy,  white,  unstable  metal,  so 
  readily  oxidized  that  it  combines  violently  with  water,  and 
  to  be  preserved  must  be  kept  under  petroleum  or  some  similar 
  liquid.  Sodium  is  used  combined  in  many  salts,  in  the  free 
  state  as  a  reducer,  and  as  a  means  of  obtaining  other  metals 
  (as  magnesium  and  aluminium)  is  an  important  commercial 
  product.  Symbol  Na  (Natrium).  Atomic  weight  23.  Specific 
  gravity  0.97. 
 
  {Sodium  amalgam},  an  alloy  of  sodium  and  mercury,  usually 
  produced  as  a  gray  metallic  crystalline  substance,  which 
  is  used  as  a  reducing  agent,  and  otherwise. 
 
  {Sodium  bicarbonate},  a  white  crystalline  substance, 
  {HNaCO3},  with  a  slight  alkaline  taste  resembling  that  of 
  sodium  carbonate.  It  is  found  in  many  mineral  springs  and 
  also  produced  artificially,.  It  is  used  in  cookery,  in 
  baking  powders,  and  as  a  source  of  carbonic  acid  gas 
  (carbon  dioxide)  for  soda  water.  Called  also  {cooking 
  soda},  {saleratus},  and  technically,  {acid  sodium 
  carbonate},  {primary  sodium  carbonate},  {sodium 
  dicarbonate},  etc 
 
  {Sodium  carbonate},  a  white  crystalline  substance, 
  {Na2CO3.10H2O},  having  a  cooling  alkaline  taste,  found  in 
  the  ashes  of  many  plants,  and  produced  artifically  in 
  large  quantities  from  common  salt.  It  is  used  in  making 
  soap,  glass,  paper,  etc.,  and  as  alkaline  agent  in  many 
  chemical  industries.  Called  also  {sal  soda},  {washing 
  soda},  or  {soda}.  Cf  {Sodium  bicarbonate},  above  and 
  {Trona}. 
 
  {Sodium  chloride},  common,  or  table,  salt,  {NaCl}. 
 
  {Sodium  hydroxide},  a  white  opaque  brittle  solid,  {NaOH}, 
  having  a  fibrous  structure,  produced  by  the  action  of 
  quicklime,  or  of  calcium  hydrate  (milk  of  lime),  on  sodium 
  carbonate.  It  is  a  strong  alkali,  and  is  used  in  the 
  manufacture  of  soap,  in  making  wood  pulp  for  paper,  etc 
  Called  also  {sodium  hydrate},  and  {caustic  soda}.  By 
  extension,  a  solution  of  sodium  hydroxide. 
 
  From  WordNet  r  1.6  [wn]: 
 
  saleratus 
  n  :  a  white  soluble  compound  used  in  effervescent  drinks  and  in 
  baking  powders  and  as  an  antacid  [syn:  {bicarbonate  of 
  soda},  {sodium  bicarbonate},  {baking  soda}]
