Soda water \So"da wat`er\, n.
   1. originally, a beverage consisting of a weak solution of
      sodium bicarbonate to which an acid (such as phosphoric
      acid) has been added to generate carbon dioxide and thus
      cause effervescence; the term now is also used as a
      synonym for soda pop. Soda water without flavoring is
      used as a beverage or as a component of a mixed beverage.
      It is typically bottled or canned under pressure so that
      the carbon dioxide and effervescence will be preserved
      until use.

   2. a beverage containing supersaturated carbon dioxide
