Table salt or rock salt has many names. Its chemical name is Sodium chloride and the chemical formula is NaCl. It consists of sodium ions and chloride anions. For its structure click here.

Is sodium chloride the ultimate salt. Its cubic, water-clear crystals are typical. In general, the crystals are colorless, but they can also be blue-violet.

The melting point of sodium chloride is 801 C; it boils at 1413 C.

Rock salt is a typical sedimentary rock that was formed when saline water dried out. The fact that salt is plastic under high pressure led, among other things, to the formation of near-surface salt deposits, the lumps of salt from which most of the salt is extracted today. In Germany, the extraction of crude salt is around 20 million tons per year.

Unlike the raw salt from which it is extracted, pure sodium chloride is not hygroscopic. Its solubility is 35.6 g at 0 C and 39.1 g / liter of water at 100 C. A solution saturated at 25 C is 26%.

Actually, sodium chloride has no special chemical properties because it is one of the Inert salts, i.e. to those who are chemically at a low potential and therefore hardly react chemically (Latin. iners, lazy).

Nevertheless, NaCl is one of the most important basic chemicals and starting material for the production of various other chemical compounds. This mainly applies to its elements, sodium and chlorine. We report on it here.

Its use as road salt or de-icing salt has the disadvantage that it corrodes metals, but also damages plants.

Table salt, on the other hand, is indispensable for the functioning of the human and animal body. Many biochemical processes depend on it and are, so to speak, the evolutionary reminder that everything living ultimately comes from the sea.

Physico-chemical interactions between salt and water play an important role in biochemical processes.
