Ionic compound

ionicionic solidionic crystals
Sodium chloride, commonly known as salt (though sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
These can be simple ions such as the sodium (Na + ) and chloride (Cl − ) in sodium chloride, or polyatomic species such as the ammonium and carbonate ions in ammonium carbonate.

Salt

In its edible form of table salt, it is commonly used as a condiment and food preservative.
Salt is a mineral consisting primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite.

Sea salt

Sodium chloride, commonly known as salt (though sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
There is no scientific evidence that consuming sea salt instead of more refined sodium chloride salts has any health benefit.

Sodium

Sodium chloride, commonly known as salt (though sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including humans.

Chloride

Cl − chloridesCl
Sodium chloride, commonly known as salt (though sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
Chloride salts such as sodium chloride are often very soluble in water.

Salt (chemistry)

saltsaltspotassium salt
Sodium chloride, commonly known as salt (though sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms.
Solid salts tend to be transparent as illustrated by sodium chloride.

Chloralkali process

The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride solutions.

Chlorine

The most common compound of chlorine, sodium chloride (common salt), has been known since ancient times.

Salinity

With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms.
Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions.

Sodium carbonate

Sodium chloride is used in the Solvay process to produce sodium carbonate and calcium chloride.
It is produced in large quantities from sodium chloride and limestone by the Solvay process.

Sodium hydroxide

It is the starting point for the chloralkali process, the industrial process to produce chlorine and sodium hydroxide, according to the chemical equation
For example, when sodium hydroxide reacts with hydrochloric acid, sodium chloride is formed:

Hydrochloric acid

HClhydrochloricmuriatic acid
In the Mannheim process and in the Hargreaves process, sodium chloride is used for the production of sodium sulfate and hydrochloric acid.
It was historically called acidum salis and spirits of salt because it was produced from rock salt and "green vitriol" (Iron(II) sulfate) (by Basilius Valentinus in the 15th century) and later from the chemically similar common salt and sulfuric acid (by Johann Rudolph Glauber in the 17th century).

Glass

Sodium carbonate, in turn, is used to produce glass, sodium bicarbonate, and dyes, as well as a myriad of other chemicals.
Fining agents such as sodium sulfate, sodium chloride, or antimony oxide may be added to reduce the number of air bubbles in the glass mixture.

Chemical equation

It is the starting point for the chloralkali process, the industrial process to produce chlorine and sodium hydroxide, according to the chemical equation
Using IUPAC nomenclature, this equation would be read as "hydrochloric acid plus sodium yields sodium chloride and hydrogen gas."

Sodium chlorate

It also is used to make sodium chlorate, which is added along with sulfuric acid and water to manufacture chlorine dioxide, an excellent oxygen-based bleaching chemical.
It decomposes above 300 °C to release oxygen and leave sodium chloride.

Aluminium

It is also used in processing aluminium, beryllium, copper, steel and vanadium.
Primarily because it is corroded by dissolved chlorides, such as common sodium chloride, household plumbing is never made from aluminium.

Mannheim process

In the Mannheim process and in the Hargreaves process, sodium chloride is used for the production of sodium sulfate and hydrochloric acid.
The Mannheim process is an industrial process for the production of hydrogen chloride and sodium sulfate from sulfuric acid and sodium chloride.

Curing (food preservation)

In its edible form of table salt, it is commonly used as a condiment and food preservative.
Salt (sodium chloride) is the primary ingredient used in meat curing.

Solvay process

ammonia-soda processSolvayammonia-soda
Sodium chloride is used in the Solvay process to produce sodium carbonate and calcium chloride.
The Solvay process results in soda ash (predominantly sodium carbonate (Na 2 CO 3 )) from brine (as a source of sodium chloride (NaCl)) and from limestone (as a source of calcium carbonate (CaCO 3 )).

Winter service vehicle

The second major application of salt is for de-icing and anti-icing of roads, both in grit bins and spread by winter service vehicles.
With the popularisation of the motor car, it was found that plowing alone was insufficient for removing all snow and ice from the roadway, leading to the development of gritting vehicles, which used sodium chloride to accelerate the melting of the snow.

Dye

Sodium carbonate, in turn, is used to produce glass, sodium bicarbonate, and dyes, as well as a myriad of other chemicals.
Direct or substantive dyeing is normally carried out in a neutral or slightly alkaline dye bath, at or near boiling point, with the addition of either sodium chloride (NaCl) or sodium sulfate (Na 2 SO 4 ) or sodium carbonate (Na 2 CO 3 ).

Sulfuric acid

It also is used to make sodium chlorate, which is added along with sulfuric acid and water to manufacture chlorine dioxide, an excellent oxygen-based bleaching chemical.
It reacts with sodium chloride, and gives hydrogen chloride gas and sodium bisulfate:

Saline (medicine)

Nasal spray often contains a saline solution.
Saline, also known as saline solution, is a mixture of sodium chloride in water and has a number of uses in medicine.

Sodium sulfate

In the Mannheim process and in the Hargreaves process, sodium chloride is used for the production of sodium sulfate and hydrochloric acid.
Unlike the alternative sodium chloride, it does not corrode the stainless steel vessels used in dyeing.

De-icing

The second major application of salt is for de-icing and anti-icing of roads, both in grit bins and spread by winter service vehicles.
Sodium chloride (rock salt) is normally used, as it is inexpensive and readily available in large quantities.
