Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash. Salt of hartshorn/sal volatile – ammonium carbonate formed by distilling bones and horns. Tin salt – hydrated stannous chloride; see also spiritus fumans, another chloride of tin.
The sodium–potassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.
Those salts that are harvested from salt mines are less commonly used for consumption. Natural, unrefined salts that have come in contact with different minerals can have a tinge of color, like pink.
SEM image of a grain of table salt. The health effects of salt are the conditions associated with the consumption of either too much or too little salt. Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are ...
Salt is used in religious ceremonies and has other cultural and traditional significance. Salt is processed from salt mines, and by the evaporation of seawater and mineral-rich spring water in shallow pools. The greatest single use for salt (sodium chloride) is as a feedstock for the production of chemicals. [3]

Humans have processed common salt (sodium chloride) for over 8000 years, using it first as a food seasoning and preservative, and now also in manufacturing, agriculture, water conditioning, for de-icing roads, and many other uses. [83] Many salts are so widely used in society that they go by common names unrelated to their chemical identity.
In chemistry, a salt is a neutral compound composed of cations bound to anions. In general, these salts are ionic compounds which form crystals. They are often soluble in water, where the two ions separate. Salts typically have a high melting point, low hardness, and low compressibility.
