Salt \Salt\, n. [AS. sealt; akin to OS. & OFries. salt, D. zout,
   G. salz, Icel., Sw., & Dan. salt, L. sal, Gr. ?, Russ. sole,
   Ir. & Gael. salann, W. halen, of unknown origin. Cf. {Sal},
   {Salad}, {Salary}, {Saline}, {Sauce}, {Sausage}.]
   1. The chloride of sodium, a substance used for seasoning
      food, for the preservation of meat, etc. It is found
      native in the earth, and is also produced, by evaporation
      and crystallization, from sea water and other water
      impregnated with saline particles.

   2. Hence, flavor; taste; savor; smack; seasoning.

            Though we are justices and doctors and churchmen . .
            . we have some salt of our youth in us. --Shak.

   3. Hence, also, piquancy; wit; sense; as, Attic salt.

   4. A dish for salt at table; a saltcellar.

            I out and bought some things; among others, a dozen
            of silver salts.                      --Pepys.

   5. A sailor; -- usually qualified by old. [Colloq.]

            Around the door are generally to be seen, laughing
            and gossiping, clusters of old salts. --Hawthorne.

   6. (Chem.) The neutral compound formed by the union of an
      acid and a base; thus, sulphuric acid and iron form the
      salt sulphate of iron or green vitriol.

   Note: Except in case of ammonium salts, accurately speaking,
         it is the acid radical which unites with the base or
         basic radical, with the elimination of hydrogen, of
         water, or of analogous compounds as side products. In
         the case of diacid and triacid bases, and of dibasic
         and tribasic acids, the mutual neutralization may vary
         in degree, producing respectively basic, neutral, or
         acid salts. See Phrases below.

   7. Fig.: That which preserves from corruption or error; that
      which purifies; a corrective; an antiseptic; also, an
      allowance or deduction; as, his statements must be taken
      with a grain of salt.

            Ye are the salt of the earth.         --Matt. v. 13.

   8. pl. Any mineral salt used as an aperient or cathartic,
      especially Epsom salts, Rochelle salt, or Glauber's salt.

   9. pl. Marshes flooded by the tide. [Prov. Eng.]

   {Above the salt}, {Below the salt}, phrases which have
      survived the old custom, in the houses of people of rank,
      of placing a large saltcellar near the middle of a long
      table, the places above which were assigned to the guests
      of distinction, and those below to dependents, inferiors,
      and poor relations. See {Saltfoot}.

            His fashion is not to take knowledge of him that is
            beneath him in clothes. He never drinks below the
            salt.                                 --B. Jonson.

   {Acid salt} (Chem.)
      (a) A salt derived from an acid which has several
          replaceable hydrogen atoms which are only partially
          exchanged for metallic atoms or basic radicals; as,
          acid potassium sulphate is an acid salt.
      (b) A salt, whatever its constitution, which merely gives
          an acid reaction; thus, copper sulphate, which is
          composed of a strong acid united with a weak base, is
          an acid salt in this sense, though theoretically it is
          a neutral salt.

      reaction, as sodium carbonate.

      (b) An alkaline salt.

   {Binary salt} (Chem.), a salt of the oxy type conveniently
      regarded as composed of two ingredients (analogously to a
      haloid salt), viz., a metal and an acid radical.

   {Double salt} (Chem.), a salt regarded as formed by the union
      of two distinct salts, as common alum, potassium aluminium
      sulphate. See under {Double}.

      (b) A salt which gives a neutral reaction.
