Detailed Product Description:
A white crystalline powder, soluble in water and glycerol, slightly soluble
in alcohol. Noncombustible.
Sodium chloride, also known as common salt, table salt, or halite is the
salt most responsible for the salinity of the ocean and is present in the
extracellular fluid of many multicellular organisms.
Sodium chloride is used in many applications, from manufacturing pulp
and paper to setting dyes in textiles and fabric, to producing soaps and
detergents. It is often used to suppress the freezing point of water with a
melting ability down to temperatures of -15°C (5°F).
Sodium chloride is sometimes used as a cheap and safe desiccant due to
its hygroscopic properties, making salting an effective method of food
preservation historically. Even though more effective desiccants are
available, few are safe for humans to ingest.
Sodium chloride is also the raw material used to produce chlorine which
itself is required for the production of many modern materials ranging
from polyvinyl chloride (PVC) to pesticides. Industrially, elemental
chlorine is usually produced by the electrolysis of sodium chloride dissolved
Sodium metal is produced commercially through the electrolysis of liquid
sodium chloride. This is done in a “Down’s cell” in which sodium chloride
is mixed with calcium chloride to lower the melting point below 700 °C.
Sodium chloride is used in other chemical processes for the large-scale
production of compounds containing sodium or chlorine. In the “Solvay process,”
sodium chloride is used for producing sodium carbonate and calcium chloride.
In the “Mannheim process” and in the “Hargreaves process.” It is used for the
production of sodium sulfate and hydrochloric acid.
