7647-14-5 Usage

Definition

ChEBI: An inorganic chloride salt having sodium(1+) as the counterion.

Brand name

Broncho Saline (Blairex).

Air & Water Reactions

Water soluble.

Purification Methods

It is recrystallised from a saturated aqueous solution (2.7mL/g) by passing in HCl gas, or by adding EtOH or acetone. It can be freed from bromide and iodide impurities by adding chlorine water to an aqueous solution and boiling it for some time to expel free bromine and iodine. Traces of iron can be removed by prolonged boiling of solid NaCl in 6M HCl; the crystals are then washed with EtOH and dried at ca 100o. Sodium chloride has been purified by sublimation in a stream of pre-purified N2 and collected by electrostatic discharge [Ross & Winkler J Am Chem Soc 76 2637 1954]. For use as a primary analytical standard, analytical reagent grade NaCl should be finely ground, dried in an electric furnace at 500-600o in a platinum crucible, and allowed to cool in a desiccator. For most purposes, however, drying at 110-120o is satisfactory.

Chemical Properties

Sodium chloride, NaCl, also known as common salt and halite, is a white crystalline solid.It is soluble in water,slightly soluble in alcohol, and melts at 804 °C (1480 °F). Sodium chloride is the most important sodium mineral and occurs naturally in seawater, underground deposits, and brine wells.Sodiumchlorideis a basic raw material for the production of chlorine,sodium hypochlorite, sodium bisulfate,soda ash, and hydrogen chloride. Sodium chloride is also used in food preparation, fertilizers, and by highway departments to control icy road conditions.

Preparation

Sodium chloride is produced by solar evaporation of seawater or brine from underground salt deposits. It also is produced by mining rock salt. The commercial product contains small amounts of calcium and magnesium chlorides.

Fire Hazard

Literature sources indicate that Sodium chloride is nonflammable.

Description

Sodium chloride is widely distributed in nature. Oceans are the vast source of sodium chloride. It occurs in seawater at an average concentration of 2.68 wt%. It also occurs in many inland saline waters and in salt deposits in sedimentary rocks, as the mineral halite.
Sodium chloride is probably the most important salt of both sodium and chlorine. Sodium chloride, common table salt, is an essential component of most food preparation, imparting flavor to food and providing the sodium nutritional requirement. Also, it is used for preserving food. Therapeutically, NaCl solution is used to combat dehydration as an electrolyte replenisher, and it is an emetic.
The most important applications of sodium chloride in the chemical industry are in making a number of important industrial chemicals such as hydrochloric acid, sodium hydroxide, sodium carbonate, and metallic sodium. It is the starting material in manufacturing these substances. Other uses are in dyeing and printing fabrics, glazing pottery, in making soap, and for curing hides. Sodium chloride is a component of many freezing mixtures.

Uses

Natural salt is the source of chlorine and of sodium as well as of all, or practically all, their Compounds, e.g., hydrochloric acid, chlorates, sodium carbonate, hydroxide, etc.; for preserving foods; manufacture of soap, to salt out dyes; in freezing mixtures; for dyeing and printing fabrics, glazing pottery, curing hides; metallurgy of tin and other metals.

Reactivity Profile

Sodium chloride is generally unreactive. Releases gaseous hydrogen chloride if mixed with a concentrated nonvolatile acid such as sulfuric acid.

Uses

Used as an electrolyte; buffers ; matrix modification.

General Description

A white crystalline solid. Commercial grade usually contains some chlorides of calcium and magnesium which absorb moisture and cause caking.

Uses

Used in biochemistry and molecular biology applications; a component of PBS and SSC buffers

Uses

Facilitates the cross-coupling of organostannanes with iodides without using palladium.1
