\Mu"ri*ate\, n. [See {Muriatic}.] (Chem.)
A salt of muriatic hydrochloric acid; a chloride; as, muriate
of ammonia.
Note: This term, as also the word muriatic, was formerly
      applied to the chlorides before their true composition
      was understood, and while they were erroneously
      supposed to be compounds of an acid with an oxide.
      Muriate and muriatic are still occasionally used as
      commercial terms, but are obsolete in scientific
      language.
