(So"di*o-) (Chem.) A combining form (also used adjectively) denoting the presence of sodium
or one of its compounds.
Sodium amalgam, an alloy of sodium and mercury, usually produced as a gray metallic crystalline
substance, which is used as a reducing agent, and otherwise. Sodium bicarbonate, a white crystalline
substance, HNaCO3, with a slight alkaline taste resembling that of sodium carbonate. It is found in many
mineral springs and also produced artificially,. It is used in cookery, in baking powders, and as a source
of carbonic acid gas (carbon dioxide) for soda water. Called also cooking soda, saleratus, and technically,
acid sodium carbonate, primary sodium carbonate, sodium dicarbonate, etc. Sodium carbonate,
a white crystalline substance, Na2CO3.10H2O, having a cooling alkaline taste, found in the ashes of
many plants, and produced artifically in large quantities from common salt. It is used in making soap,
glass, paper, etc., and as alkaline agent in many chemical industries. Called also sal soda, washing
soda, or soda. Cf. Sodium bicarbonate, above and Trona. Sodium chloride, common, or table,
salt, NaCl. Sodium hydroxide, a white opaque brittle solid, NaOH, having a fibrous structure, produced
by the action of quicklime, or of calcium hydrate (milk of lime), on sodium carbonate. It is a strong alkali,
and is used in the manufacture of soap, in making wood pulp for paper, etc. Called also sodium hydrate,
and caustic soda. By extension, a solution of sodium hydroxide.
(So"di*um) n. [NL., fr.E. soda.] (Chem.) A common metallic element of the alkali group, in
nature always occuring combined, as in common salt, in albite, etc. It is isolated as a soft, waxy, white,
unstable metal, so readily oxidized that it combines violently with water, and to be preserved must be
kept under petroleum or some similar liquid. Sodium is used combined in many salts, in the free state
as a reducer, and as a means of obtaining other metals (as magnesium and aluminium) is an important
commercial product. Symbol Na Atomic weight 23. Specific gravity 0.97.
