salt

salt

1. A compound formed by the interaction of an acid and a base, the ionizable hydrogen atoms of the acid being replaced by the positive ion of the base. 2. Sodium chloride, the prototypical s. 3. A saline cathartic, especially magnesium sulfate, sodium sulfate, or Rochelle s.; often denoted by the plural, salts.sal; [L. sal]
acid s.a s. in which not all of the ionizable hydrogen of the acid is replaced by the electropositive element; e.g., NaHSO4, KH2PO4.bisalt, protosalt;
artificial Carlsbad s.a mixture of potassium sulfate, sodium chloride, sodium bicarbonate, and dried sodium sulfate; a laxative.
artificial Kissingen s.a mixture of potassium chloride, sodium chloride, anhydrous magnesium sulfate, and sodium bicarbonate; an antacid and laxative.
artificial Vichy s.a mixture of sodium bicarbonate, anhydrous magnesium sulfate, potassium carbonate, and sodium chloride; an antacid.
basic s.a s. in which there are one or more hydroxyl ions not replaced by the electronegative element of an acid; e.g., Fe(OH)2Cl.
bile s.'sthe s. forms of bile acids; e.g., taurocholate, glycocholate.
bone s. See bone-salt.
common s.sodium chloride
diazonium s.'ss.'s of a theoretical base R-N=N or R-N=NOH useful in histochemistry to demonstrate tissue phenols and aryl amines or with enzymatically released naphthols and naphthylamines to form the chromophore azo group -N=N-; diazonium s.'s contain only one R-N=N group, tetrazonium s.'s contain two, and hexazonium s.'s contain three; examples include fast garnet GBC base and naphthol AS.
double s.a s. in which two different positive ions are bonded to the same negative ion, or vice versa; e.g., NaKSO4.
effervescent s.'spreparations made by adding sodium bicarbonate and tartaric and citric acids to the active s.; when thrown into water the acids break up the sodium bicarbonate, setting free the carbonic acid gas.
Epsom s.'smagnesium sulfate
Glauber's s.sodium sulfate
hexazonium s.'sdiazonium s.'s that contain three azo groups.
Reinecke s.an ammonium salt prepared by fusing ammonium thiocyanate with ammonium dichromate; dark red crystals; used in the detection and analysis of primary and secondary amines, including amino acids; also used as a reagent for mercury.
Rivière's s.potassium citrate
Rochelle s.potassium sodium tartrate
Seignette's s.potassium sodium tartrate
smelling s.'saromatic ammonia spirit
table s.sodium chloride
tetrazonium s.'sdiazonium s.'s that contain three azo groups.
