{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.
