* 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.

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

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. -- Alkaline salt (Chem.), a salt which gives an alkaline reaction, as sodium carbonate. -- Amphid salt (Old Chem.), a salt of the oxy type, formerly regarded as composed of two oxides, an acid and a basic oxide. [Obsolescent] -- Basic salt (Chem.) (a) A salt which contains more of the basic constituent than is required to neutralize the acid. (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. -- Epsom salts. See in the Vocabulary. -- Essential salt (Old Chem.), a salt obtained by crystallizing plant juices. -- Ethereal salt. (Chem.) See under Ethereal. -- Glauber's salt or salts. See in Vocabulary. -- Haloid salt (Chem.), a simple salt of a halogen acid, as sodium chloride. -- Microcosmic salt. (Chem.).

Same as Rochelle salt. -- Salt of soda (Old Chem.), sodium carbonate. -- Salt of sorrel (Old Chem.), acid potassium oxalate, or potassium quadroxalate, used as a solvent for ink stains; -- so called because found in the sorrel, or Oxalis. Also sometimes inaccurately called salt of lemon. -- Salt of tartar (Old Chem.), potassium carbonate; -- so called because formerly made by heating cream of tartar, or potassium tartrate. [Obs.] -- Salt of Venus (Old Chem.), blue vitriol; copper sulphate; -- the alchemical name of copper being Venus. -- Salt of wisdom. See Alembroth. -- Sedative salt (Old Med. Chem.), boric acid. -- Sesqui salt (Chem.), a salt derived from a sesquioxide base or analogous compound. -- Spirit of salt. (Chem.) See under Spirit. -- Sulpho salt (Chem.), a salt analogous to an oxy salt, but containing sulphur in place of oxygen.
